IPv6 and Amazon EC2

I saw a bunch of people discussing this article. Basically it is saying that after 20 years IPv6 has only reached 10% deployment rate. I actually expect that number to start growing faster now since IPv4 addresses have been exhausted. At a certain point the cost of rolling out IPv6 will be less than horrible solutions like Carrier Grade NAT if the ISP doesn’t have enough IP Addresses. I always expected them to start rolling out IPv6 on Cell Phones given the number of devices and the growth rate, but I haven’t heard about anyone doing that yet.
