I'd love to hear about this (or MAP-E, or lw4o6) as well especially with 
regard to CPE support.  My preferred CPE vendor keeps punting on it 
(though they do claim to support 464XLAT), and I'd really like something 
to point them to that will show them it's a "real thing".  Getting rid 
of state at the CGN as is (or can be, at least) necessary with 464XLAT 
seems like a real boon while placing minimal additional burden on the CPE.
