Xbox as Streaming Audio or iTunes Client

[selowitch]

I wonder if it's possible to play iTunes music (or other streaming audio) on the Xbox when it is connected to a network that includes my Macintosh?

Would that be great? I could play my iTunes material on the stereo in my living room while the Mac lives in the office....

Unless the music mixer software has anything involved, I can't think of any way to get a xbox to play streaming media over a network. Regardless of the computer that tries it.
