Isn't this basically the same proposal that APNIC turned down and
referred to IETF who then turned it down as well?  Basically you end up
with a system in place that allows v4 communications only between places
in North America and only between operators who choose to deploy it?

It still doesn't guarantee you will be able to communicate with anyone
outside of North America.
