We may have it at last - I am not saying who just yet as it is all beta/test software and field trials, but we should have something real soon now.
It looks like working with a manufacturer closely, even providing one of our broadband lines in their R&D offices, may have paid off.
We are testing and giving feedback, but looking very encouraging. Testing so far is that IPv6 "just works", and even though it has wifi and a 4 port switch and both DSL and PPPoE WAN, it is sanely priced to be our new "free with service" router.
We'll put details for field trials on the web site soon.
P.S. and perfect timing as comcast starts IPv6 in the US
