As there are various kinds of NAT, it is a waste of effort to try
to have a universal NAT traversing protocol.

Instead, we should define some standard NAT for which simplest
NAT traversal is required for widest range of applications.

As end to end NAT with complete end to end transparency does not
require any NAT traversal for all applications, we are done.

So true.
