It's a very interesting idea, although I would like to see some more details. Trying to create a peer to peer online video platform is something I've considered in the past, however, I was never able to find a scalable solution for competing with centralized services that use CDNs to deliver video to home internet connections which are quite slow.
Admittedly I was trying to use the Bittorrent protocol which meant that if the uploader of an unpopular video turned off their computer then it would stop being available to users and it had to be stored on home PC not servers, so maybe you won't have that problem using whatever technology you have.
