My 7206VXR shows that my ipv6 is being cef switched.... Of course the
entire platform is CPU based so who knows.

I do have native ipv6 on one, and I'm tunneled 2 hops away on the other,
still within the purview of the carrier's network.

Read the NPRM carefully, you already can get a /32 PI free of charge if
you have a /21 or larger (might even apply for a /22, can't remember).
You pay the larger of the two ARIN fees, not the combination.

Not demanding the support is a very chicken/egg situation. I demand
support even for things that won't have v6 capability and have no demand
so the features are there when I need them. (I do this with plenty of
features I don't currently use but would like to in the future). Waiting
until you have an urgent need before starting the process of requesting
the feature is something I wholeheartedly encourage my competitors to do.
