> If you want a p2p system because you care mostly about removing servers as a bottleneck, then this may not be an issue, but if you care about removing servers because you don't trust intermediaries, then this only gets you half way there.
This is, actually, truly peer-to-peer. Those are connections to the bootstrap nodes, you can set your own bootstrap nodes if you want but you do need to be seeded with a few initial peers to find new peers. If you want to establish a browser-to-browser connection, you will need some server to help setup the WebRTC connection; this is the unfortunate reality of browsers. However, you can (theoretically^) connect to arbitrary non-browser IPFS nodes over a websocket connection (that's what's happening here) without some "blessed" node acting as the rendezvous.
^Unfortunately, there's a bit of a wrinkle:
1. Most non-browser IPFS nodes don't listen on websockets by default. The transport is still experimental and and has some bugs.
2. If you load IPFS from an https origin, browsers won't generally allow you to establish connections to non-https websocket endpoints. Unfortunately, even if you enable listening on the websocket transport on your IPFS node, you'll end up listening on an http (not https) websocket. This is because IPFS manages the encryption of the connection itself (IPFS addresses, or "peer IDs", are cryptographic hashes of public keys) and doesn't use (or play well with) the CA system. To work around this, the bootstrap nodes have nginx proxies out in front that to handle HTTPs connections. Most (all other?) nodes don't.
