i agree with mostly everything you said but i think your calculation is wrong. to figure out how to map addresses not only the destination port can be taken to account but the addresses themselves and the source port too. that makes 28k (that figure is questionable too) concurrent connections per single connected IP and port on the far end. i am also somewhat certain if this would become a real issue the fix would probably involve mapping connections using more state like sequence numbers in TCP or similar things instead of abandoning this idea entirely and for good.
