Integrate (something similar to) PeerTube
PeerTube is an awesome idea that uses WebTorrents to torrent content from a server. Pretty much, if 3 million people want to watch a large video, the server might go down, because too many requests are being made.
But, with PeerTube, that won't happen, because once a user has the content, the server will say to anyone else who wants the content "just take the video from that guy." and not have to transfer a giant video.
Of course, stream checksums and that stuff will have to be made, but it look really promising.
*I am not affiliated with the PeerTube project, I just find it very interesting.
