WebTorrent [1] can be used to run BitTorrent on the web.
It's actually integrated into the Brave browser which is a nice feature. Other browsers might catch on soon.

This essentially splinters the world into the bittorrent and webtorrent halves, which makes it far less useful.
The DHT remains split for now.
