What the post fails to mention is that any piece of software or hardware that wants to act as an AirPlay receiver requires a key issued by Apple. The key used by most (if not all) of these unauthorized AirPlay receivers comes from an Airport Express (http://www.macrumors.com/2011/04/11/apple-airplay-private-key-exposed-opening-door-to-airport-express-emulators/ http://www.macrumors.com/2011/04/11/apple-airplay-private-ke...). I support the idea of using an iOS device as an AirPlay receiver (I have a copy of AirView safely backed up in hopes of using an old iPhone or iPod touch as a way to turn any speaker into an AirPlay speaker), but they had to have known that using an unauthorized private key was going to get them in trouble. I'm not familiar with the inner workings of the protocols behind AirPlay, but assuming it transmits unencrypted data (because the client is trusted), then it would be possible to losslessly strip the DRM from protected files, something that could land Apple in hot water with the movie/TV studios.
