Now that you mention it, it never occurred to me that Snake's radio transmitted video as well. "Did you like my new sunglasses?"

If you could reserve a small portion of the radio bandwidth to broadcast a thumbnail + low bandwidth compressed representation of the face movements, you could technically have something similar without encoding any video (think low res, eye + mouth movements).

Nice feature for many to one video conferencing as well. Though I don’t know if the organizers will agree.
