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.
