I feel like I've seen this pop up a few times now, but this is really, really cool stuff. The only thing that concerns me about the growing popularity of using WebRTC is the security concerns around unknowingly joining a p2p network like this for potentially any site you visit. It's not hard to imagine what a bad actor could do to content before passing it along, or more simply, the fact that your true IP is exposed.<p>Curmudgeony security issues aside, this undeniably feels like The Future™ and a big deal to watch out for. It's also one of those cases where a creator / maintainer makes a huge difference for long term viability in my opinion. Feross is crazy smart and has been working with all the related tech for a while now (via PeerCDN, Instant.io, etc, etc), and is just an all around respectful, nice guy, which is important for the continued development / community aspect.
