> Are there systems of communication between parties on the public internet that can guarantee native IPv6 on both ends, don't want to use IPv4 NAT, and don't want to set up a point-to-point VPN? WebRTC is one example of something that can greatly benefit from having publicly routable addresses on clients (in practice this tends to mean IPv6). If both clients are behind IPv4 NAT that doesn't allow hole punching, they will need TURN (or media) server in order to communicate. While clients might be close to each other (e.g. same apartment building), that TURN server can have horrible routing for this set of clients. For example, it could be in Europe while both of the clients are in west coast of USA (and that's not even nearly the worst case).
