I*do* think NAT is simple, but that's not the basis of my argument.
I'm merely arguing against the suggestion that "NAT is broken in a
number of ways" when the problems mentioned turn out to be either
contrived or non-problems.

Using NAT, for outgoing traffic is simple. However, as soon as you want remote access to computers behind your firewall, things get "interesting". There is no simple way to access multiple computers with the same protocol. You have to resort to tricks such as non-standard ports, or, as you mentioned in another note, relaying ssh. A VPN will work (assuming no NAT address clash), but you might not have one handy. It might also be blocked by the local firewall.
