Personally, I think that NAT's interference with the
communication between hosts is similar to the way in
which error-detection and retransmission interfere
with realtime voice communication, as described in
Saltzer's end-to-end paper:
http://web.mit.edu/Saltzer/www/publications/endtoend/endtoend.txt

It seems that the end-to-end principle is more
of a metaphor for how to look at the design problem
rather than a hard and fast rule.
