Thanks Stephan,
I learned a lot from this code.

But I think my solution is much easier to handle.
I don't need to define a view for every interface.
I just have to implement my traverser which is a one liner.
ZCML is also reusable, it could be easily integrated into zope as a 
standard traverser ;)
