Dynamic assigned addresses mean that the BRAS the customer terminates on 
can hand out a range out of a pool assigned to it.  This means I can 
have a single route in my routing table for a whole BRAS (maybe 20k 
customers) vs 20k routes and associated processing when the dsl goes 
up/down/etc.

My car is designed to go 200km/hr or more.  But the roads are 
implemented poorly.   IPv6 is design to do everything for everyone, but 
the reality is the implementations aren't there or it's not practical.  

Mobile just creates more mess, I'm trying to make this simple and make 
it work.
