It's only a single stream; you won't be able to do multiple cameras. The question is what software to use. I think you'll want Airplay mirroring, probably off of the iphone. That's going to have the best camera. You may be able to mirror the camera app or something like photo booth, but as I don't have an AppleTV, I'm not sure how possible that is.

EDIT: Here's what you need to do: http://lifehacker.com/5867058/use-airplay-to-watch-your-iphone-4s-camera-on-apple-tv

It's swipe to the left twice (ie, get to the controls, rather than the app list), but other than that, this should do what you want.

Be sure to use the rear camera on the iPhone.
