I was simplifying a bit. About a third of our customers are dynamic
802.11 hotspot customers. Since those are each single hosts, I can't
foresee allocating more than a /64 per hotspot with each host getting a
single dynamic address. But this perception could be based on a great
deal of ignorance of the future of these types of connections. (maybe a
vlan per customer with each vlan using a /64, but the still only gets
its one host address.)
For static connections to residences I'd need at most 2000 /48's. A
/36 would be plenty.

Yes, that would be great. I'm hoping that ARIN does revise their fee
Frankly I don't care if we get a /36 or a /32. I'd just like a IPv6
allocation of 'equivalent' size of our current IPv4 allocation, whatever
that equivalent size is, without increasing our fees. Ideally I want to
be able to assign each end user a /48, have enough /48 networks
available in a continguous block for forseeable customer growth and
advertise one aggregate route to each of our upstream AS's.
