Pulse audio is very easy to use in a networked situation. It only took me a few minutes to get running using the provided settings tools.
There's a good wiki about it here:

(Note that the warning at top is not quite correct. You can use kde3 with pulse, you just can't use the aRts server with it. You have to set kde up to use alsa.)
