I'm still waiting for WebTorrent to be implemented in more clients (including libtorrent, which AFAIK underlies Picotorrent). I'd love to be able to quickly deploy headless WebTorrent video seeds, especially if they were sequence-aware (sending chunks in order, possibly incl. MPEG DASH format, though that is patented somehow); and maybe commodity BitTorrent + WebTorrent CDNs could become commonplace.
