-We can't build a FOSS video streaming alternatives to YouTube, Dailymotion, Vimeo... with a centralized software.
-One organization alone cannot have enought money to pay bandwith and video storage of its server.
-So we need to have a decentralized network (as [Diaspora](https://github.com/diaspora/diaspora) for example).
-But it's not enought because one video could become famous and overload the server.
-It's the reason why we need to use a P2P protocol to limit the server load.
-Thanks to [webtorrent](https://github.com/feross/webtorrent), we can make P2P (thus bittorrent) inside the web browser right now.
