Kinda what I figured. It's a shame as it's no doubt some kind of 
coreaudio thing in there and once the desktop stuff is out the way, it 
should be quite simple to take to the iphone...

I think you mean a server here rather than a client, but I get the jist. 
I guess an app that implements it's own player (e.g. the vlc app 
available for jailbroken devices) could use it's pulse output layer... 
Not exactly mainstream, but could provide some interesting fiddling 
opportunities!
