You might want to look at rplay and (what was the other? 'netplay'?). 
They're client/server audio playback packages. 

Also, this isn't of any help, but I'd like to generalize the question: 
has any work been done on a "media layer" for X, with synchronized
playback of audio and video? Something like QuickTime(tm) is _badly_
needed.
