You talk to the sound daemon based on $AUDIO and then $DISPLAY. You do 
synchronization via X once the X synchronization extension is brought back into
happiness.

Keeping the ability to have a sound daemon store samples isnt a bad thing
providing you manage the denial of service issues from sound uploading sanely.
The library needs to be able to find these as well as the server ideally though
so that direct audio works for people with high end cards.

Folks might also want to glance at OpenAL which is a different problem area but
one we need to be aware of long term if we want to do positional audio (and 
even left/right stereo hacks for positional beeps work interestingly well)
