And you don't even need native IPv6.  DS-lite will work on top of
6rd and should give a better "experience" than NAT444.  If you can
route Class E between the CPE and the 6rd BR you can give your
customers stable IPv6 addresses today.  It just requires 1 more
routing entry in the CPE for the 6rd BR.

You can then do 2:1 with DS-Lite and half the address space you
were handing to customers is reusable.
