Have you ever tried to deploy IPv6 (even if only in a lab environment)? I have worked with several companies (ISP and enterprise) and once they stop thinking "I want to do everything in IPv6 in exactly the same way as I have always done in IPv4" and actually look at the features that IPv6 provides them they are usually much happier with IPv6 than they were with IPv4.

I am sure that a century ago people who were used to horse and buggy transport thought that cars were annoyingly complex and that having to put petrol in instead of hay was a huge problem. But I am very glad that in the end they adapted instead of convincing other people to make cars run on hay ;)

Just joking of course, but seriously: we need to look at what the best solution for the future is, not at ways of avoiding having to learn something new/different.
