In fact, were someone to use those "worst current practices" to build some generic p2p VPN software, even old games could leverage it to allow someone behind a CGN to host.

A CGN that obeys these requirements will allow NAT traversal by virtue of having an Endpoint-Independent Mapping behaviour. That is the BCP. Not port prediction.
Even better. So, architecturally P2P compatibility with CGNs is a solved problem waiting only for the software to shake out. Expect some growing pains in the first generation CGNs which largely vanish in the second. Regards, Bill Herrin -- William D.
