Identity for web 3.0

http://agilewiki.wiki.sourceforge.net/Identity

I've been looking at web 3.0 and find that I very much agree with the ideas. I would categorize web 3.0 as being a p2p system which supports multiple points of entry (home, office, cyber cafe), where the nodes support information fusion, have pluggable applications and some native reasoning. And this is exactly what I've been working on for so many years now.

Today I've been thinking about an easy way to validate user identity in such a network. See the above link for details. It is reasonably easy to do and I've introduced only one new idea--categories of passwords.
