Maybe I'm not understanding the problem you're worried about
here, but as far as I can tell, remote employees using VPNs
are still a problem with a new allocation: If an enterprise
has two remote sites, each served by a different CGN, those
two sites will get address conflicts in the new space. A new
allocation doesn't solve that problem.
Agreed. Also, as more and more organizations use kits and
third-party software of various sorts to permit people to work
from home via VPNs, the notion of a 'pure "consumer"'
installation becomes more of a myth in various part of the
world. Consumer applications, yes. But, from an addressing
standpoint, a LAN is either pure-consumer or it isn't. There
are fewer of the former now than there were when 1918 was
adopted. Worse, many of those that exist today are likely to be
converted in the next year or two. An addressing policy that is
designed around the assumption that we can break addresses up
into "safe" pools that then breaks when "consumers" put in
applications that try to create VPNs is likely to be a far worse
support nightmare (and one of the expensive case-by-case
variety) than actually dealing with the issues, as a group, now.
