Doesn't having some kind of central record of keys go against the principle of PGP? Unless you're just talking about having a name attached to each key, but not exactly a DNS for key id's... I'll admit I'm a little confused.
Not at all. The point is to have a centralized, distributed key distribution mechanism, similar in concept to the PGP Public Keyservers, but which scale much much better. The concept is similar to a DNS of PGP keys (think of the DNS model, not the DNS implementation) where you have keys distributed based upon site. For example, MIT could server MIT's keys, and CMU would server CMU's keys. This does not go against PGP in any way. In fact, it augments PGP wonderfully. How else would we be able to have a world-wide white pages of PGP Public Keys? -derek
