Depends on what you mean by "informed." They have a pretty well-informed 
idea about their own networks.

How well-informed are the participants in 6man? Is it obvious that once 
someone subscribes to 6man and reads the background of this doc, they 
will be supporters?

Is there clear consensus?

I haven't checked the list of meeting attendees against ASNs with IPv6, 
but I would expect it's much higher than average. No idea whether it's 
higher than the networks of IETF attendees, but then, most IETF 
attendees aren't network operators.

Maybe someone from the IETF NOC could weigh in. I don't know whether any 
large WiFi operators are here. Do you know any? If their input is 
important, maybe we should go find some?
