Camera output as a texture on a plane?

I was wondering if there’s possible to assign the output of a camera as a texture on a plane in Maya, and get realtime feedback from the camera onto the texture?

I could always render out sequences from the other cameras and then apply them as textures, but I’d save a lot of time if there was some way to do this without rendering every camera separately first.

I doubt there’s something like this within Maya by default, but I thought maybe there was a plugin or something to do this?
