In the specific case, this might take a new translator box that is not
budgeted.  Yes, I know renumbering costs staff time, but many organizations
find it much easier to justify staff time than capital expenses.

There's already a commitment to renumber here.  Tim, my major point was
that the enterprise here should, when renumbering, install infrastructure
that makes possible future renumbering easier.  Are you opposed to this?
DHCP and such exist today, but I'm not sure I would say fully functional
and tested address translators do.  They may very well be in the near term.

I'll agree that address translation will work in some, but not all
situations.   The problems are less in pure routing than in network
management, DNS (especially reverse mapping), etc.

I don't think we are in philosophical disagreement, but what the technical
implementation should or can be.

There is no good way for man to fly.
There is an excellent way for man to be flown in airplanes.
There isn't always a need to fly.  Requirements analysis can fix things at
the end system, with application-dependent solutions ranging from
videoconferencing to ICBMs.
