Per previous threads, Citrix Metaframe 1.8 with FR 1 installed enables audio to to be streamed to the epod. . .but you have to have the client license.
But, I don't understand why you can't control your servers soundcard with the epod.
Basically, using the epod as a remote control for your 'jukebox' server hooked up to your stereo. This is what I really want to do with an old computer laying around. Several epoders seem to imply that it works with Windows Media Player 7.1, but I can't get it to work.
I may have to go the x10 route as someone did (busdepot?). I don't know what the sound quality would be like, but it's better than the other methods available.
