This guy looks at 4% uptake and says the sky is falling. I look at 4% uptake and say we're in really great shape. According to this guy's somewhat pessimistic view, we're at least two years from the beginning of IPv4 shortages. We already have 4% uptake when there's very little incentive to do anything about ipv6. When the pressure comes on a little bit, uptake will skyrocket. The great thing is that there's a network effect here: the more people get on ipv6, the more benefit there is to each additional punter. It's more and more attractive as more people join. I think we'll have no problem rolling this snowball.
