IPv6 Over Social Networks
An anonymous reader writes "A new RFC has been published this morning to significantly speed the deployment of IPv6. With IPv6 over Social Network (IPoSN), '[e]very user is a router with at least one loopback interface,' and 'Every friend or connection between users will be used as a point-to-point link.' It is noted that latency on the network can be very high, though."
IPv6 is being deployed. For example, this shows the growth in the IPv6 routing table size during 2008: http://www.potaroo.net/ispcol/2009-03/fig7.jpg
You can also check out http://sixy.ch/ for a list of IPv6-accessible web sites. It's growing weekly.
Google has launched their IPv6 trusted tester program, making many of their services reachable over IPv6.
