My apologies for not being clear:

As I posted just before in reply to MarkA - I'm hoping that for the 
MAJORITY of customers that I can use PD and dynamic /64s (or whatever) 
local to a BRAS. 

My FEAR is that people ("customers") are going to start assuming that v6 
means their own static allocation (quite a number are assuming this).   
This means that I have a problem with routing table size etc if I have 
to implement that.

I'm still not convinced though that, given DHCPv6 is going to be a 
reality for DNS assignment etc, that stateless autoconfig is needed and 
thus /64 doesn't have to be the smallest we assign.
