And to open up those incoming connections on IPv6, we'll invent some other variant of UPnP so users don't have to manually go punch holes into their firewall to allow peer to peer connections. IPv6 doesn't solve the problem of everything in the internal network being unable to accept incoming connections. With a NAT you need to set up port forwarding. With IPv6 you need to punch a hole into your firewall. Either way, home users will not be doing it by hand... we'll invent some protocol to do it and that protocol will have security issues.
