Correct, I don't see a need to change Zope's structure, but some tools to
use it's features in a non linear manner would be nice.

3) dynamic creation or shaping of properties based on navigation paths.
4) alternative rendering of content based on instance
	4a) 'if  in a' else  'in b'

Does that make sense?
