Easy & Affordable Wireless Audio

While I'm sure the sound quality of this system is dubious, i think the concept is very very cool. An extremely simple multi-room audio solution, based on a source that (just about) anyone owns. $299 for the base station kit + one wireless speaker, $129 for each additional speaker.

I think the combination of iPod, wireless audio, and now these itty bitty "digital" amp chips all have enormous potential . Wireless active speakers, powered by ultra efficient and small digital amp chips.

What kind of system would you build?
