I really think the hosting cannot be centralised. If its centralised, its a honeypot for the censorious, the avaricious and the stalker-y, henceforth referred to as government.
I love Bittorrent, but I am yet to see a good integration with the HTML world.
https://ipfs.io is a newer protocol that integrates better, and clients are available for every major platform. Its still a bit slow out of the gate for high-def long-form video, but the more people who watch (and cache) an IPFS-hosted video the faster it gets!
