based on which cost model? I can assign a single /48 to a BRAS and
push /64's to end bridge devices... that seems 'cheaper' to me in
terms of route-bloat in my core... Just curious as to where your
figure comes from really, thanks.

in general I really don't support this fictional 'classful ipv6': /32
= provider, /48 = customer, /64 = LAN. I believe it's wasteful and
unnecessary. Especially in a world that's been pushed to smaller
subnets/broadcast domains and an increase of bandwidth per LAN
required. there are some interesting contradictions in the ages-old v6
address planning and current world networking...
