To add to that, there's also the fact that any user of any ISP that throttles/blocks torrent traffic is probably going to have the same experience. Plus the fact that there's at least two people I know whose ISPs actually cut users' down speed by double of any up speed (in order to "passively" cut down torrenting without actually restricting it). So PeerTube becomes less a YouTube replacement and more an interesting implementation of streaming video via Bittorrent (which some clients already support).
