NAT is a dead end. If the Internet does not develop a way
NAT, the Internet will die. It will gradually be replaced
that are more-or-less IP based but which only run a small number of
applications, poorly, and expensively.
...or you will see an overlay network build on top of
NAT+IPv4 that abstracts the shortcomings away - aka what the
peer to peer networks are doing. End-to-end addressing...
Precisely. Just what is this fetish about keeping the IP address the same as
the packet travels?
If there is a way for the host to determine that it is behind a NAT and to
request external registration of necessary ports the whole process can be
made completely transparent to the hosts at each end.
