Yeap... but...

We are an ISP fucusing on individuals (most) and business (minority, but growing).
Because of nature of our business, we decided to have central BRAS and large L2 (in future MPLS) network.
So, most of our subscribers are connected via "ethernet all the way", native DHCP (no PPPoWhatever).

Both - Cisco/Ericsson(RedBack) - for their BRASes have not yet implemented this access method for IPv6..
They have it on roadmap, but it will take a while for first releases and much more before they will be stable enough to
put them in production.
2 years at least I suppose..

Now, imagine that there is a lot of ISPs like us with the same problem, however, very often lager scale...

(I suppose that Juniper and others are at the same stage).
