Control the Apple TV
So that it can be turned off, play/paused, etc.
For example my Flic is next to my bed, and my TV is on the other side of the room. The Flic could be used to power on/off (toggle), play/pause, fast forward, rewind, and go back (menu).
This would be great because then the remote could just be used to select a movie, then the Flic could just be held in the palm of the hand so that the remote could be left aside.
