It would make sense to keep the discovery/social aspect separate from the media storage and allow for multiple sources for the same video in case some go down. And possibly you could upload to many places at once.

(repeating myself here, it would be nice to have)

(A) Torrent (like) protocol where you pay for download/stream and get paid in bitcoin for actively hosting it. Where people could sponsor the streaming of a video (or a part of it) if they wanted more eyes on their content.
