David M. Cotter: We could, but the bigger issue is that "pause" doesn't really make sense with an app like Airfoil. Without remote control, it's more like "mute" since the source application keeps playing. So we're holding off until we can do it right.

Ross Collins: Not to worry. For now at least, we'll continue to support 3.0 and up.

Matt Reimer: Probably not if we expect Apple to approve it.

Ben: Stay tuned.

Marcus: Unless I misunderstand you, we actually already have volume control via Airfoil Speakers (and Airfoil Speakers Touch). The volume slider in Speakers is linked to the slider in Airfoil for that receiver, over the network.

Peter Witham: Thanks for the very kind words.
