How can you say it's not getting anywhere? Last time I checked, Feross is pushing an incredible amount of modular, high quality code. His #webtorrent IRC room is highly active and has even become a meeting place of sorts for people working on other decentralization projects. The idea that client integration is the most important part is entirely your opinion, and it's an opinion that not many agree with. In a completely browser-based form webtorrent could still have the potential to cut media hosting costs by a factor of 100.
I explained why in my comment. The protocol needs to be integrated into desktop clients and it hasn't been. Moreover, feross is not trying to convince client developers to incorporate webtorrent, nor is he submitting patches to those clients.
foobarqux, actually he is planning on doing that. I met with him just the other week, so I know this for fact. It just takes time, maybe you could help contribute?
