Now, there's an interesting concept. If the server in a small office were able to get an audio connection to an amplifier or public address system, all in the office could "remote control" the music. It would also make it possible to use the server as a "music on hold" source for a PBX.
Anyone want to hazard a guess as to the difficulty of enabling control of a Linux mp3 player via CGI/Perl? I have little experience with things at that level.
