Ben: Apple prohibits this sort of thing, in addition to limiting you to 50 promo codes per release. That would not be at all viable for us. No, as I said, even if we could get this approved by Apple, we’d need to start charging for Airfoil Speakers Touch (or at least an in-app purchase).

Like I said, we’ll see what happens – for now, you can simply use Airfoil on your Mac to send any audio to Airfoil Speakers Touch, instead of sending direct.
