Informal SAML teaching tools

I've been getting requests for technical/white papers on SAML, and I don't 
know where to send people.  The specs are a little too opaque so far, and 
the press articles are too vague.  Does anyone have any papers or 
presentations that they'd be willing to share (e.g. on the SSTC web 
page)?  I think that spending some resources on education at this point 
would be a very good thing.

Thanks--
