Tangential, I think adding support of http://webtorrent.io/ by bridging webtorrent peer with bittorent peer would greatly increase/revive the popularity of the protocol

exatorrent supports webtorrent peers already

That's great news! Is it designed to reusable as a library, for example to build a peertube native desktop client?

You can use

https://github.com/anacrolix/torrent

for those cases.
