I would much prefer DHCPv6 to work "just like DHCPv4" - which means 
that the great bulk of our customers are configured with an unnumbered
interface on a BRAS, and all the relevant IP configuration is on the
DHCP server. The key here is avoidance of customer-specific config on
the BRAS.

It's beginning to sound like IPv6 is going to be considerably more
complex than IPv4 here - which is certainly going to slow its uptake...
