No.  Not ISPs.  In my experience, ISPs have become quite active in investigating ways of deploying IPv6 in ways that are useful to their customers. This obviously makes sense since it is the ISPs that are going to be the ones first impacted by the lack of IP addresses. 

The folks not interested in paradigm shifts, as demonstrated by the lack of significant IPv6 deployment, are pretty much everybody else (modulo the tiny percentage of geeks and early adopters).  These folks do not want to care how things work.  The fact that IPv6 makes them have to care is probably the worst failing of IPv6.
