I have considered this in the past, but the list isn't all that long and many of the products listed support multiple platforms, requiring the replication and maintenance of multiple instances of the same product. 
I take your point, but it may still be worth doing some splitting. At least for those single platform items. Have one section, multiplatform, to handle those others. I, for example, could then skip over any iPhone or Mac specific sections, as I do not run those platforms. For that matter, splitting up by platform may not be unreasonable, even with duplicate entries. People look for software within the platforms they run / available to them.
I do wonder if instead of repeating the list periodically, you should just keep the editing the original post. That way there's only one real copy of the list floating around. People will know to always go to the first post of the thread to find the current list.
Each time the list comes out I rescan the list looking for updates or changes. Perhaps instead of reposting the entire list, you could post 'software x entry added/updated', OP list (with link) updated. I might not then need to rescan the entire list each time. Given the density, and the age of my eyes, I find the process of re-reviewing the list, and trying to remember what software I've already checked out, somewhat painful. (But thanks for being here at all, I SURE appreciate it!)
I sure get you are volunteering your time to do this, and I SURE appreciate that. This is all just CDN$0.02.
It would be useful if you could expand the list / not have it quite so dense. And I think it would be useful if some additional comments per package accompanied each list item.
Here are some suggestions:
(Candidate additions noted. Some not D-Link, or even IP Cam, specific.)
D-Link Surveillance Center <- NOTE: Although blue text, not a link. Could you fix the link or remove the blue?
D-Link Surveillance Center - Platforms: D-Link DNS-325/345 Cost: $0 (Last Updated: 01/2013)
- NAS software. (For those like me not intimately familiar with D-Link model #'s.)
D-ViewCam (Desktop Client) - Platforms: Windows Cost: Free (Last Updated: 11/2011)
- very capable 'server' software, if you can get it to run. Reports of infinite loop settings changes / software restarts. (So try it on a different computer.) Worth checking out. (The free gem of the list, if it will run for you, and you have the appropriate product.) Note: Takes over entire screen (but can be minimized) - particularly irritating with multiple monitors.
- enterprise class software likely suited for home, but perhaps not elsewhere unless running Windows Server, due to the 10 connection limit of non-server Windows OS's.
D-ViewCam (Android) - Platforms: Android Cost: Free (Last Updated: 12/2012)
- requires an instance of D-ViewCam (above) to connect to.
IP Camera Viewer - Platforms: Windows Cost: Free (Last Updated: 09/13/2012)
- very basic, no frills, "Is this thing turned on?" app.
iSpy - Platforms: Windows Cost: Free Installation Guide: DCS-930L (Last Updated: 01/2013)
- very capable 'server' software, free for single PC instance only, subscription based otherwise. Free version provides no remote access to or from. Web site lists an extensive and rich capability far beyond most, including D-ViewCam above - but for a not inconsiderable cost. Interface not particularly 'pretty'.
mydlink Lite (Android) - Platforms: Android Cost: Free (Last Updated: 11/2011)
- connects to your mydlink.com account. Note: each instance must log in using the mydlink.com e-mail address and password - which reveals the cam's admin password. Share prudently. So, perhaps not the nanny cam software you'd let your neighbour use.
mydlink.com (* ADD *) - All browsers (full functionality ONLY with Internet Explorer) - see web site. Free, only with/for appropriate / box indicated D-Link Cloud product purchases.
- MUST use Internet Explorer for full functionality. Free IE plug in installed permits camera to tunnel through the connection (e.g. RTSP) - such tunnelling unavailable in other browsers. (Live view still available, though, via Quicktime.) IE also enhances with access to microphone and local recording of live footage. Note: each instance must log in using the mydlink.com e-mail address and password - which reveals the cam's admin password. Share prudently. Unlike the direct web interface, no 'view only' userid / access possible. Therefore, a 'view my own cam' service, not a 'view my cam' equivalent.
- for SD cams, such as the DCS-2132L, the only mechanism other than direct web interface or physical access to card, able to access the files locally stored on the SD card.
- web based, and rather slow, particularly due to the encrypted tunnelling, as a result.
native web interface (* ADD *)
- different products with different capabilities. e.g. With appropriate firewall hole poked, remote view my cam functionality possible, albeit 'ugly'. May in and of itself, with no additional software, provide sufficient remote access for your needs.
Motion - Platforms: Linux Cost: Free (Last Updated: 03/2013)
- no gui. Likely not a complete solution in and of itself.
Yawcam - Platforms: Windowse Cost: Free (Last Updated: 03/2013)
- currently reporting difficulties for some, likely due to problems with later java's. (From memory, I can no longer make it run because of this) worth investigating as you journey on your learning curve.
- excellent and comprehensive functionality, although a rather bland interface. A good choice post "does my camera work at all" stage, and, for some, entirely sufficient.
Zoneminder - Platforms: Linux Cost: Free (Last Updated: 08/2012)
- a complete solution, but not for the non-Linux fainthearted. Surprisingly rich and easy to use, once familiar with the interface. Greatest difficulty most have is in getting their (USB Webcam) hardware to work - a non-issue if that's not your hardware. e.g. IP Cams. VM's available - no need for a standalone Linux running computer until you're ready and feel the need.
ManyCam - Platforms: Windows, Mac Cost: Free - http://www.manycam.com/ - "The best free live studio & webcam effects software!"
- found via http://www.yawcam.com/forum/viewtopic.php?f=4&t=1264 "You should be able to use more than one webcam software simultaneously. You can you something like 'ManyCam', Its free and fairly easy to use. It simply acquires the Cam, Then feeds it to other software. Its also a fun program. "
- perhaps useful here if only to feed USB cams elsewhere on your network into other software.
(- I've not used it myself.)
Dorgem - open source Platform: Windows Cost: Free - http://dorgem.sourceforge.net/
- discontinued, capable, but USB cams only (?). Perhaps useful / excellent here if only to feed USB cams elsewhere on your network into other software.
TeboCam - open source Platform: Windows Cost: Free - http://teboweb.com/WebCam.html
- capable, but USB cams only (?). Perhaps useful here if only to feed USB cams elsewhere on your network into other software.
vlc - open source Platform: PCs Cost: Free - http://www.videolan.org/vlc/index.html
- although a media player, also capable as a relay and/or recorder, e.g. RTSP in (Open/Network Stream) out to multicast (apparently). Multicast being finicky / problematic / bandwidth hogging, over wifi. Definitely useful as a sanity check.
- multiple cam view apparently possible via Mosaic add in, http://wiki.videolan.org/Mosaic.
IP Cam Viewer Lite - Platform: Android Cost: Free - https://play.google.com/store/apps/details?id=com.rcreations.ipcamviewer
- just works. Particularly useful for standalone / no PC sanity check. Give to your coworkers at need, for a 'nanny cam' without involving them with the complexity of PC access or playback, if that's not their particular need. (Others more directly involved may need more, on their computer, but they'll still like this as they move around during their day.) Can record.
I get if you want to trim this list, given it's "DCS-compatible" orientation, however, I got here for that purpose, then discovered such is but part of this ecosystem. These other entries were items I found useful along the way to get here, before being willing to put out the $$$ for an IP cam. I was then able to leverage that experience once I did get the IP Cam. Others may need to traverse the same learning curve, and this may help them do so more quickly.
So, although you may wish to trim and keep focus, a link or two to other such useful or more generic lists, would be useful. Answering the question: I need more, are there other user vetted useful links to which I can go to for more information on 'all this stuff'.
