I'm not sure - I've heard of an Android app that can send video to an AppleTV, but I haven't heard of an app that can receive video from an iOS device. If you know of one, I'd appreciate a link.

AirPlayer from Erica Sadun would work: http://ericasadun.com/ftp/AirPlay/

However, she mentions that you can't stream music to AirPlayer due to RAOP: http://en.wikipedia.org/wiki/Remote_Audio_Output_Protocol

which, I guess is not true anymore due to the parent link :)

But it does seem to show that iTunes was indeed checking keys before sending to an Airport Express, but that AirPlay (for video) wasn't affected. As far as I know, AirPlay is not much more than HTTP Live Streaming.

Also of interest in the same area (though this is an iOS app, so could technically include some key checking without knowing it): https://github.com/nto/AirView
