IP<->IP translation (was re: Statements against new.net?)

I don't think the issue of portability is separate from that of
interesting names or addresses. One of the useful aspects of DNS
is that it is portable. If you renumber ("move") then you have
DNS (translation table) reflect your new address. And in the
interim, you have a temporary forward (borrowing the old IPs
until DNS propagation gets the new IPs into circulation all over).
As was indicated, the problem with this is that there's no
system to ensure that the forward is temporary.

If an IP<->IP translation system is implemented, this means that
a scalable method for updating everyone's tables must be devised.
What would stop people from caching translation tables the way
they cache DNS?

Yes it does, but unlike the land grab for interesting 
domain names, people worry less about having an
interesting IP address, especially if they know it
will be portable.

No, think of this as a resolution step that happens
in a matter analogous to DNS resolution, but for
IP<->IP address translation.  

At the beginning of a session, a translation request 
is made to resolve to the logical address (and all
IP addresses are considered logical at first, just
like all telephone addresses are considered logical
until they are resolved).  The translation is made,
and the physical IP address is cached and used for
the session.

Obviously, end stations do not request this 
translation today so it would first require a 
protocol definition.

This suffers from exactly the same problems wrt address portability
that DNS does, doesn't it? Looks to me like you just described DNS,
but used an IP address instead of /[a-zA-Z0-9-\.]+/.
