I've got to be missing something...

What about all end-node nets use the "this" network for all internal 
nodes, with minimal NAT (add/remove actual network prefix) at the 
external interfaces.

DNS zones, obviously, have to know/supply the actual network prefix
as well as the 'this network' node address.

Is there anything else that passes (potentially) _off_network_  IP
addresses in the data portion of the packet?  ('on network' addresses
can be reconstructed from 'this' network, by the simple expedient of
combining the 'this' network host address, with the actual network 
prefix from the packet source address.)
