Kyle Baxter in reply to this post by me:

That’s all possible through an iOS application and AirPlay, but there’s no way something like that could gain traction following that route. Telling users to (1) purchase an Apple TV, (2) purchase an iOS application, and (3) stream it to their Apple TV is so convoluted few regular users would get past the first step.

That is a great point, I may have to rethink this.
