Would it be possible, for example, to take the new HTC one which has an IR Reciever as well as bluetooth and everything else in it, to create an app for the google play market that would connect to an app you would create for xbox, and open both up at the same time, connect the phone to the xbox, and broadcast whatever you wanted over your phone to the xbox? (such as movies, or the phone screen, ect)
That would be one hell of an app....
