Or seperate the end system identifer from the routing goop. This
solves lots of problems (while introducing others).
even if you do this the end system identifier needs to be globally
scoped, and you need to be able to use the end system identifier
from anywhere in the net, as a means to reach that end system.
DNS is a bright and successfull example of such deal.
It could be better to use domain names as system IDs but today
there is too much software which assume IP as system ID
(network ID of system in real).
otherwise you're in about the same shape as with a NATted network.
