FYI there was a couple of hours work done on this today at the sprint in Paris. It seemed to us the the next necessary step in Sidneis branch was to make Zope2 traversal adapters for non-zope3 objects. This work has now started, in the form of refactoring the BaseRequest traversal into Zope3 type traversal chunks that we can make adapters of. Current problem: getRole is called with the entry_name unless the subobject was gotten via a getitem interface, when it's called with None. As we want to do the getRole part outside of the name traversal, we don't know in which way the name was gotten. So we need to solve that tomorrow somehow.
