Mac-based AirPlay service allows device-to-Mac playback

AirPlay is a very, very cool technology. Unfortunately, if you don’t own an Apple TV 2 or other capable receiving device, it’s not going to do you much good. (If you have the cash on-hand, for $99, the Apple TV mark 2 is a pretty sweet purchase. Just saying.) So I decided to figure out a way that people who didn’t own an Apple TV, or who were on the road with their iPhone and a laptop could actually use AirPlay streaming “backwards” — from their iDevice to their Mac.
