did you miss the part where before this could happen there would be growth
of ipv6-only end nodes and thus ipv4 would be a nonuniversal protocol, NAT
or no NAT?  as before, i don't see why DREN would prefer non-RFC1918 IPv4
over RFC1918 IPv4 if neither one will have as many endpoints to talk to as
IPv6-only -- which is the point in the timeline we're discussing.
