IPv6 is a real protocol, it has significant deployment of the Internet, and there are now whole data centers that are IPv6 only (e.g. FB), and there are plenty of use cases of IPSEC/IPv6 that could benefit for performance improvements just as much IPv4. This vendor mentality that IPv6 is still not important simply doesn't help matters. :-( Tom
