My original text remains true, because I tend to hear IPv6-only advocacy from vendors and policy folks more than 
operators - even more so versus operators of commercial ISP networks.  But I take your point, that operators ahead of 
the IPv6 deployment curve are most likely to stand up with that opinion.

Of course, the "network effect" being what it is...  Your network being 100% IPv6 doesn't solve the overall problem of 
reachability.  I think your example of 4% traffic from VT is applicable - you will have to worry about IPv4 
connectivity, in one form or another, until it diminishes significantly.  It's a bit like a tragedy of the commons.
