Yes, but I don't know of an analogous concept for zope's or python's 
object trees (ignoring restrictedTraverse). I always think of them as 
doubly linked list, without an easy method to get to the "root".
I thought of restrictedTraverse always just as a utility for the 
translation of paths into objects.

Why do we have an aq_parent, when there is also a 
restrictedTraverse('..'), or, conversly, why is getPhysicalRoot() a 
python (product) only method while restrictedTraverse('/') does the same 
and is unrestricted?
