This is a very interesting area which is currently being worked
in the IETF IDS Group. In particular, they are progressing toward
a naming plan which applies to user names and CA names in X.509 
certificates.

The proposed naming plan take advantage of the domain name which
everyone is already familiared with, and very scaleable.

BTW, the guide you produced was excellent reading.
