Greetings all. Have 3 ATV2's in the house and would sometimes like to 'remote control' the playing one from the iMac. I know I can do that if I am using AirPlay from iTunes ON THAT MAC, but I am running SL Server using my old C2D MBP to serve the iTunes library to all the home devices. What I would like is a 'remote app' I can run from any of the Macs in the house. Is there anything out there like that?
