I don't really see this as a problem.  Getting desktops over to dual  
really is last priority in my book.  The important thing is getting  
and content providers dual-stacked, because, the first systems that will
get forced to IPv6-only will be those that come on-line after IPv4  
Likely the bulk of those will be end-users of some form or other.

Again, I really don't see this as a problem.  Enterprise Desktop  
of IPv6 really is last priority and for those enterprises that don't  
to get it done in time, they are the ones that will suffer the impacts.
