Thanks for understanding.
To me it just seems like a crazy idea of assigning a /64 subnet (that can otherwise fulfill requirements of 18,446,744,073,709,551,616 hosts) to a residential CPE which today uses at the max 5-10 IPv4 addresses on their LANs.
I think because we have been working with IPv4 and have been really careful about not wasting IPs due to the limited address space, maybe its that same mindset which makes me uncomfortable looking at multiple /64s going to a single DSL end-customer etc. :)
Anyway, next time I am using autoconf and assign a /64 to a residential CPE, I'll just go blind and convince myself not to think about wasting all these addresses....

it is not that i disagree with your arguments. it's just that i lost
the selfsame arguments some years ago. the current generally accepted
'wisdom,' with
little supporting measurement, is that iv6 address space
is effectively infinite and the ipv6 routing table is a very scarce
resource. that this resembles pigs at a trough constructing a barrier
to entry is not a widely held perception.
