What is sure is that they include the key. From [0]: > The other major feature in Airfoil Speakers is the new Enhanced Audio Receiving option. With an inexpensive in-app purchase, your iOS device becomes a full-fledged mobile AirPlay receiver! This is only possible with the leaked AirPort ROM private key. As soon as I saw the title on HN I thought that was the most likely cause of the removal. Occam's razor and all. Including the Apple private key in Airfoil Speakers Touch was, if not stupid, at least a very bold move from Rogue Amoeba.
