I agree with John here. I am not going to speak for content providers, but I
have heard them raise serious business concerns about the lack of
infrastructure deployment. They make their living on responsiveness, and an
extended transition with its associated unpredictability without native
routing potentially impacts business (ie: so far behind their peers in
perceived quality that finances are impacted).
This is a grand game of chicken. The ISPs are refusing to move first due to
lack of content, and the content providers are refusing to move first due to
lack of infrastructure. We are going to hit the end of the IPv4 pool and
have a panic driven deployment rather than a well planned one.
I just hosted a session with enterprises that are actively deploying IPv6 to
start distilling best-practices, and it is clear that something similar is
going to have to happen for ISPs. I am not ready to organize something just
yet, but if you are interested I will hang around the beer-n-gear.
