thank you! This is vastly improved!

I did notice one error that I introduced.... with the move from SAML 
1 to SAML 2, the navigation page can no longer redirect directly to 
the IdP.

I also noticed an error that crept in when you translated from my 
initial crude image -- EzProxy can be configured to know which 
resources are Shib-enabled; if the resource is Shib-enabled, it will 
redirect the user straight to the resource, rather than thru the 
proxy portion of EZP....

this is useful because it allows instructors, for instance, to create 
"pseudo-permanent" url's that they include in course home pages; 
these url's won't change if a resource moves from IP-access control 
to Shib-based access control.
