Agreed,and many customers will switch without knowing it.
If Comcast swapped my cable modem for a V6 capable modem, and if as a part of routine upgrades, my Dlink-whatever got swapped with one that has native v6, I'd be on v6 without knowing it. My Vista, Win7, Mac and Solaris clients would 'just work'. I.e. - when I dropped a /64 onto my home lan - consisting of a handful of laptops and an OpenSolaris server - my Vista, Win 7 and Mac picked up the V6 network and started using v6 w/o even a re-boot.
The harder part is making a decision to shut off IPV4. It's at that point that you have to make a service availability decision.
