Keith, Well, we agree on the utility of having multiple PKIs. We disagree on the need for a PKI that happens to cover a specific name space that underlies the vast majority of IP-based communications, or at least you disagree on the desirability of that specific PKI given the reality of who runs which TLDs. But, you don't offer any suggestions on how to address the need that a DNS-based PKI satisfies. I guess we should just leave our disagreement at that. Steve
