Protocol diagram of OpenID

I have produced a protocol diagram summarising the OpenID protocol.
This was to help myself understand the OpenID protocol better, and
also to serve as a discussion aid in a brief talk I gave.

I think this may be of wider interest, particularly to make it more
accessible to those used to reading standard protocol diagrams, so I
have put this on my website: (PDF 44KB)

Any comments, corrections and suggestions are appreciated.

Thank you,
Steven Murdoch.
