I'm curious whether and how you plan to enforce the distinctions
between (1) and (2), and (3) and (4). It seems to me that unless you
do some moderately intrusive checks to ensure that they're responsive
on both addresses, a customer could simply disable their IPv6 stack
and go "haha, now I don't have to contribute to the environment, but I
still get the lower price".  (Here I'm assuming you're talking about
either home users or colo, since it's not totally clear to me which of
your services you're describing above.)
