In fact many ISP's only allow their clients to update the forward maps since
they don't want to set those blocks of addresses into SWIPPED mode.

It's quite possible to allow individual machines to update
their reverse records without having to delegate the name
space to the customer. TCP is a strong enough authenticator
for this role.

er... both are registering things in the DNS. manipulation
of the farward map is occasionally easier than manipulation
of the reverse map... which i think is what you are trying
to say.
and it is often true that those who manage the forward DNS map
are -NOT- the same folks that manage the reverse DNS map.
