Attached is an updated architecture document for your review and comment,  It includes the following changes:

        1. Updated data access section from Mario.
        2. Updated federation section based upon last week's teleconference
        3. Updated and reorganized security information.  This is my attempt to incorporate changes from GGF-15.

As a reminder: I currently hold the document write lock.  Mario has a sub-lock on the Data Access section
