IPFS, in particular, plan to have native browser support via a Javascript dependency. There was also PeerCDN (and bunch of similar clones), but they all don't tend to stick around for long or get widely used even though the setup is supposedly one line.

The problem with PeerCDN and other WebRTC based solutions is that they can't solve the DNS DDOS problem. Since the WebRTC API needs a server for the handshake to start communicating between 2 peers directly.

Eh, but the DNS server isn't necessarily the same as the bootstrapping server for the WebRTC API, and in most cases it generally would not be.
