Personal IPv6 exit IP as alternative to port forwarding

[CentralPivot 0]

With IPv6 allowing practically infinite IPs it should be possible to assign a dedicated IPv6 address to each connection, allowing incoming connections to any port to be forwarded. This would be a great way to circumvent the port forwarding restrictions on IPv4 that exist because multiple clients have to share the same exit IP, and I think would make for a nice optional feature.
