Sorry, I guess I should have been a little more clear the AMEN was for 
the last  part of Ted's statement, "unless you have MS buy-in, then you 
can just forget it. And MS is backing IPv6."

I completely agree, XP shouldn't really hamper IPv6 adoption, it just 
won't be much of a driver for it. I have IPv6 running on my XP desktops. 
  It works OK.  It would be nice if it did IPv6 for DNS transports, but 
it is not required in a dual-stack world.

I only includes the earlier part because I wanted to mention 
DirectAccess and though it could very well be a driver for Windows 7 and 
IPv6 adoption.  If you support networks for MS types you might want to 
look at DirectAccess.  My MS types are already pushing hard for us (the 
Network people) and the security people to support DirectAccess.
