While I suspect that most in the networking world views IPv6 as the right answer to the address crunch, the reality is that broad-scale technology changes don't happen within the period of 4 years. Sure, consumer electronics is one thing. But wholesale re-engineering of the Internet is a completely different proposition. Most commercial ISPs are not even advertising IPv6 service yet. It is far more likely that you'll see ISPs providing RFC1918 addresses to their non-commercial customers in order to charge premiums to those who really need to be publicly addressable. All the doom and gloom press is helping to spur the discussion. This is a good thing. But let's be realistic. Business is not going to let IPv6 become Y2K11.
