Has any thought been given to the mechanisms and methodologies to be
used for interconnecting separate Internets with overlapping address
spaces?  Granted, there's only one Internet at the moment, and we be
it, but there may come a time where more than one Internet springs up
along side of the existing Internet, even in the DoD, with completely
separate administration mechanisms, including address assignment
(although still based on the internetworking protocols of choice at
the time, whether that's DoD IP, or ISO IP down the road).  And these
side-by-side Internets may have some interoperability requirements.
Can interoperability be successfully implemented at an Internet (or
read Level 3) position in the protocol stack, or do we have to resort
to some application level funniness?  I know this may seem to be a
silly or somewhat naive question, but there are actual situations
where this could eventually arise.  Any thoughts? 

many thanks,
