Peace,

As far as I understand you mean that
IPv6 implementation not depend on operators equipment, but depend on end users CPE?
Not sure if I understand where this conversation is headed, but anyhow: IPv6 deployment, as of now (as well as long ago, like 2-3 years already), is entirely dependant on the network middleware, which is switches, firewalls, and whatever middleboxes (and their configuration, which sometimes gets inherited from the previous generation of devices).
Endpoints are not an issue. These are, mostly, new. Out of the rest of these (already a minority), most of them are software-updated. I know an ISP who switched one day to IPv6 only and only got a thousand support requests for what should be believed to be a hundred thousand customers database. And they just resolved all of that in a week.
