As I asked before - I'm really keen to actually do this stuff - but all 
I get is people who haven't done it telling me theory and not how it 
works in practise in a real ISP of some scale.  

Telling customers "well, you might get renumbered randomly" isn't going 
to work, no matter what the theory about it all is.  They do crazy and 
unexpected things and bleat about it even if you told them not to.  At 
worse they stop paying you and leave!

My hope is that PD will be used for the majority and statics will be 
small in number.  My FEAR is that customers have already been 
conditioned that v6 will mean statics for everyone because v6 has so 
many! (This has already been the assumption many have made from the 
customer side).

Tell me about it.  

As I asked before - has ANYONE done this before?   ie.  fully 
dualstacked to customers?  Or is it still theory?
