Skype is an interesting case because of its peer-to-peer nature. Given the state of v6 deployment and operational experience[1], and especially given the fragility of tunneled IPv6 connections[2], there is potential for a lot of broken links. --Steve Bellovin, http://www.cs.columbia.edu/~smb [1] All concerned are mystified about why my office machines can't reach [major site] via v6, even though traceroute6 from both ends shows the packets reaching the same network.
