Video Conferencing with Apple TV, a webcam and a distant wifi connected mac

Hello,

I have a new large screen LED TV that I set up as my conference room presentation device in my office.

I use appleTV to stream to it wirelessly from my mac at my desk away from the conference area or from my iPad.

I would like to use this new LED TV to do FaceTime and Skype. Therefor, I would love to hook up a video camera to the Apple TV if possible.

Any advice?

It would be too far to hook up with a wired cable to my computer.

thanks!

Peter
