I'm guessing part of the issue here is folks appear to be talking past each other. It might be helpful to be explicit about what your view of the "IPv4 CGN implementation problem" is. For example, IPv6 _could_ be a solution if both the CPE and the CGN supports IPv6 and a way to tunnel v4 through v6 (no idea if anyone does this).
