> WebTorrent has DHTs working in the browser, not sure how much more decentralized you're talking about.
Not sure about how things work now, but IIRC WebTorrent web peers could not connect to native BitTorrent peers. Instead they would connect only to WebTorrent Desktop peers and other Web peers. The WebTorrent team of course is doing incredible work, and they've been able to convince some of the native torrent clients to support Web Torrent - so it kinda works in practice.
So for a new protocol, the hard part would be to make all the non-browser peers speak WebRTC - which is nowhere as easy/robust as writing a TCP/UDP based peer [1].
