My wishes are by order of preference.
1. I wish I could easily connect USB drives to the DNS-323 unit. This is particularly important for making backups of the files on the unit, and to backup many gigabytes of files takes hours (or even days). This could also be useful, of course, to share another drive on the network. Even better, would be to also allow to connect the drive directly, with USB to a computer.
2. I wish it would exist a web access to the FTP server. The company where I work has a firewall and without web access I can't access my files.
3. I wish there would be a way not only to schedule the download of files, through an FTP server, but also, to schedule the upload of files through FTP. This is useful again for making automatic backups, maybe even to remote servers on the net.
4. Possibility to edit the itunes server playlists right from the admin panel (it's a text file, I'm sure it's easy to allow this). Right now itunes server only gives us a huge list of musics. Other option, would be, of course, for the box by default to provide us with more playlists (ex: 90's, 80's, top rated, recently added, recently played, top 25, genre, rating, artist).
5. I wish there was a way to use the http server (goahead web server) that comes with the DNS-323 to host our own simple websites (asking PHP and MySql is probably too much, but of course, they would be welcome).
6. Automatic mirror bakckup with other D-Link products (ex: another DNS-323 or the DNS-313).
7. Encryption. I have no idea how this could be done or if it can be done. But I believe it would be interesting to have some automatic encryption on every file saved. If someone turned off the drive, the password would have to be entered again. This is useful in case somebody steals our DNS-323.
