sounds great but it fucks up P2P in residential connections, where it is mostly used due to ipv4 address conservation. You can still have nat in IPv6 but hopefully I won't have to deal with it

In practice, P2P over ipv6 is totally screwed because there are no widely supported protocols for dynamic firewall pinholing (allowing inbound traffic) on home routers, whereas dynamic ipv4 NAT configuration via UPnP is very popular and used by many applications.
