I am in favor of an approach like this that minimizes the overhead of
using sound when possible. However, there are a few questions not
addressed here:
	Q. How would network-transparency be addressed?
	A. Most likely, talking to a local sound daemon (for
	   hardware only capable of a single stream) would be the
	   same as talking to a remote sound daemon.

	Q. How would sound events be handled?
	A. Currently esd stores the sound samples and plays
	   them back at the request of applications. One possible
	   solution is having gnome-session (or another per-session
	   process) perform this duty, and then devise a way for
	   applications to easily talk to this process.
