This plugin allows you to create Apple TV devices from Apple TV's that have been jailbroken and have aTVFlash installed. Included with aTVFlash is an extra called AirControl which allows remote client applications to get information about currently playing media and control the Apple TV as if with an actual physical remote.
Get it on our open source repository.
Jailbreaking and installing aTVFlash is solely the responsibility of the owner - see the FireCore.com website for details. It really is not for the faint of heart...
