Folks,
My question to the community is: assuming a network based IPv6 to IP4 translator is in place (like NAT64 / DNS64), are IPv6-only Internet services viable as a product today? In particular, would it be appropriate for a 3G /smartphone or wireless broadband focused on at casual (web and email) Internet users? Keep in mind, these users have NAT44 today.
You may also want to read up on Dual Stack Lite (DS-Lite) <http://tools.ietf.org/html/draft-ietf-softwire-dual-stack-lite-02>, 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.
