VLC goes through the motions, even prompts for username/password, but is not able to show it. But using HTML in a browser allows you to do it (fill in 2 values, IP-address and SerialNo):
<html>
    <body>
   <table border=0 >
   <tr>
   <td align="center">
            <APPLET name="cvcs" CODEBASE="http://192.168.x.y/" CODE="xplug.class" WIDTH=640 HEIGHT=480>
                <param name="RemotePort" value=80>
                <param name="Timeout" value=5000>
                <param name="RotateAngle" value=0>
                <param name="PreviewFrameRate" value=2>
                <param name="DeviceSerialNo" value="PutYourCodeHere">
            </APPLET>
   </td>
...Repeat above for multiple...
   </tr>
   </table>
    </body>
</html>
