Well, if grouper represents a collection of objects (groups, members, 
attributes, roles) which refer to other objects, then, for a given interval 
of time, I would like to find any references which have been added or 
removed, scoped to a single object, by kind of object referred to, or at 
greater depth of reference.

Does that make sense ? I want to know if something's relationship web has 
changed.
