I often watch the "moving map" of my flight, especially on overseas flight. While I prefer aisle seats, I do miss just looking out the window. It struck me that if the airline could include a simple camera pointed down at the ground (or maybe 2 cameras, one on each side) and include this video stream as one of the options for viewing, it would be a relatively simple way to enhance the experience.

Is anyone aware of a feature like this? Is this as easy as I think it might be?
