> other apps that would lend themselves to being shown on one (big) screen, and controlled on another (small) screen. Think: games.

:) That's something I wanted to do way before AirPlay, by using the iOS device as a web-server of some sort and display the big screen part of the games through a web browser (on laptop, game console...). In particular, one idea was for games like Pictionary or Taboo: the small device is a controller as well as the private part of the game (with the hints).

However, I never implemented anything due to my lack of experience with iOS and the fact that it seemed that the game console web browsers were fairly limited... contact me if anyone would like to do something around that though, even if just for fun!
