@Gavin Andresen
Several questions:
1. In the post-NSA-snowden era, are you sure it is wise to participate in creation of a centralized mechanism, which governments can easily control ? Why would we trust *any* CA ?
This is not just a hypothetical concern. It is a known fact that not only the NSA, but hacker groups have copies of CA certs, which they use to perform MITM attacks against HTTPS. The CA model is insecure.
