there's no question that it's easier than the ipv4 case.  congrats are
in order on that point.

however, at size 10**4 and above, renumbering of this kind will be 
expensive.  and at size 10**5 and above, it will be constant/overlapping.

my point was, that's a big reason why folks will ask "why not just use NAT?"

now i'm thinking, please don't make NAT any harder than it already is.
