Re: They should never have cried wolf

But IPv4 devices can't talk to IPv6 devices that doesn't co-exist in the IPv4 address space. This lack of forward compatibility (I mean, can't you use SOME kind of adaptation like a special pre-addressing packet?) scares people away from adopting IPv6 because they KNOW there WILL be some of us stranded on IPv4 for better or for worse. No one wants to strand customers.
