You may also want to read up on Dual Stack Lite (DS-Lite)
presuming you haven't. I know you mentioned you didn't like any
dual-stack solutions, but the thing about DS-Lite I like is that it has
no problem with RFC1918 overlap of different customers, since the CGN
uses a tunnel ID in the connection/NAT table in addition to the other
typical data. I just wonder how it will scale, since each device, or a
gateway the device goes though, will require a IPv4-in-IPv6 tunnel to
the CGN box(es). Also, it doesn't require a DNS-ALG like NAT64/DNS64.
