Nigel: We'll see - that would require charging for Airfoil Speakers Touch, which we've thus far avoided. For now, to send iTunes to your iOS device, you can use Airfoil to send iTunes.

Rob: Yes, this all requires Airfoil 4, which has been out for 8 months now. You're going to need a 10.6 machine to use it all.

As far as the App Store description, we'll watch to see if this is a common issue - most users are on Airfoil 4 by now though.

Come check us out when you've updated!
