Reverse engineering is really cool and has great benefits, for example, TUAW’s very own Erica Sadun, has managed to reverse engineer AirPlay’s playback video so you can play it on your Mac. How so? Well, here’s some info:

What AirPlayer does is create and advertise a custom Bonjour AirPlay service that pretends to be an Apple TV.
