It is also useful to look at this from the perspective of convergency. If 
we put that to the extreme (and who knows if that is realism or not but a 
policy is valid for quite a while), there might in the future only be one 
IP network. Closed islands will then be carefully encrypted, use high grade 
end-to-end encryption) and advanced fire walling will do the rest 
(whatever). At the same time other portions are the Internet as we know it. 
So if we look at a potential for an extremely converged future, what does 
not connected mean? Today, yes, in 30 years from now, who knows?

In my view it is best to do away with "private" address space concepts and 
plan for permanently fully de-conflicted networks. Connected or not. In my 
work, I see the consequences in NATO and national defence networks. I can 
imagine that these consequences of not using public IP space are the same 
if one merges 2 large cooperations and tries to integrate the infrastructures.
