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.
