This is over 50% of the leaves out there (conservatively). At what point is there sufficient market penetration of the technology to consider rolling IPv4/IPv6 interoperability/capability on the core routers and switches (something short of 100%, I would hope)? 4) Is it maybe that Sun, HP, Intel, Cisco, IBM, and the telco's, aren't all quite ready yet? 5) Admittedly, I haven't had the bandwidth to follow IPv6 all that closely. But, IPv6 has been pregnent quite a long time.
