It seems so incredibly unlikely that end-to-end connectivity (i.e.
without NAT, NAPT, or other middleboxes) is going to increase in future.
Say end-to-end NAT (<draft-ohta-e2e-nat-00.txt>).
Port restricted IP by end-to-end NAT keeps the end-to-end
connectivity and effectively extend IPv4 address space by
factor of 100 or 1,000.
The point is to keep the end-to-end transparency is to let end
systems aware of and help NAT functionality.
Current loss of end-to-end connectivity by existing NAT boxes
will be restored if the boxes are replaced/upgraded to have
end-to-end NAT capability.
