Currently with v4 I have one (majority) of customers where they have 
dynamic addresses.  For those I'm happy to use PD - but my point was 
that people are starting to assume that v6 WILL mean static allocations 
for all customers.  This is my fear, is NOT being able to use PD for the 
"residential grade" customers.  Having to provide static allocations is 
a problem if I have multiple POPs in a geographic region as I can't 
summarise and get the redundancy I want. 

(If I commit to a customer they have a static range then I can't easily 
change it on them - esp if they've done things like used the addresses 
statically in DNS etc as our customers are want to do).

Has anyone out there actually done an implentation, across DSL of PD?  
If you have PLEASE let me know on list/off list/by dead letter drop in a 
park.  Especially interested in CPE etc.
