I don't think is failing ... On the other way around: looking at the adoption perspectives and compared with other technologies, transition stages, and so on, is going much faster than expected ...
About 4 years ago, I predicted that v6 would be very significant 8-10 years from then. I think we're right on track. As someone else noted, Windows Vista will have v6 enabled by default. There's also a version-independent network API. As a consequence, most applications written for Vista will be v6-capable. Vista will ship next year; 4-5 years after that, most desktops will be running it, and hence will support v6, including the applications. We're also seeing planning for conversion (i.e., the U.S. Defense Department) and deployment in some parts of the world. An obvious corollary to this is that ISPs should be planning their v6 offerings now, too. This means routers, databases, operation support systems, CPE for cable and DSL ISPs, etc. Those that don't are likely to find themselves bypassed. --Steven M.
