I am very excited by this news (assuming my non-tech brain understands this). I love Airplay, Apple TV, Airport Express, etc., but I've always been bothered by the network aspect of it. My devices seem to fall off the network periodically, and some devices - like the Apple TV - seem to get bothered when you have no internet connection as a part of the network, which is frequently the case for me. I like - what sounds to me to be - the "directness" of this new protocol. And it seems like it will really open the door for car stereo Airplay. (I feel like reasonable, basic car stereos should be playing nicer (no wires, no FM dependence) with iPhones by 2011. Maybe this will fix that.)
