but...). Now, if 1.2.3.4 has proper matching forward/reverse DNS lookups,=
 I don't see how people behind someone else's NAT pose a problem.

Remember, we're talking about matching hostnames to reverse lookups.

My understanding is that we are talking about:

(a) Doing a reverse lookup on the IP address, and getting a name.
(b) Doing a forward lookup on that name, and making sure you get the
right IP address back.

That works fine with or without NAT.

The hostname that is configured on the actual workstation is
irrelevant.  (And is also unknwon (to the target of the connection) for
many protocols.)
