I am actually more concerned with the CPE problem and how to make 
autoconfiguration work for end users.

For instance, should we assign /64 to end users and have them do whatever 
they need (subnet to /80 if they need more than one network)? We need to 
provision routes in whatever routers connect to customers, which I guess 
is the FIB/RIB-problem mentioned above?

Is there general agreement that IPv6 requires a router at the customer 
prem to scale (ISP doesn't want to know what the end user devices are)?
Also, is it ok to statically assign /64 to end user or should end user be 
able to switch addresses (some like dynamic IPs because it's not 
persistant over time and like the "privacy" you get by changing IP all the 

I haven't been able to find a BCP regarding the end user equipment and how 
to configure it, does anyone have any pointers?
