Me too. I hope the feature makes it into v5. And kudos for being patient with all of the posters who didn't quite understand what you wanted. I would have lost it...
I think it's a fairly obscure feature I'm asking about, so I don't blame people at first for not getting it. Especially when it does work with the Remote app, just not any other apps.
Hopefully Apple will add this feature in a future beta. If the iPad can handle streaming video via AirPlay, surely it can handle sending audio to multiple devices.
This feature is really the holy grail for me: Music throughout the house, no central computer/iTunes needed, no super expensive Sonos system to buy, no wiring to put in, guests could access the system with their own iDevices and play their own music.
