Talk Amonst your selves!
I haven't heard anything about it. Can you tell us more about what it is, and what it does? Will it be a subscriber service, like the satellite radio? Is there a sampling rate or protocol that would limit sound quality like CD? Can it be added or adapted to existing tuners?
