Precisely. Expect organizations who have had sufficient positive results 
with their NAT444 deployments to not limit it to new users only, for 
many reasons, some of which they cannot be faulted for.

Some of these organizations will as a result have more available 
resources then anybody else put together.

So either NAT444 is so horrible that only new users can be put into it, 
or there is a new sheriff in town, along the lines of the golden rule.
