I am not sure if there has to be a "canonical" registry. For example, most western countries have multiple competing credit rating agencies reporting on individual identities and the system seems to work okay on that aspect. I will give my ideas more thought down the road. We have already tried this with PGP but it had too many issues to be practical. In any case, whatever we end up building is going to be better than DNS which is one entity with too many pairs of hands controlling it, all the way from ICANN to the registries to malicious social engineers.
