It's an intriguing post but I think you need to provide more  
information on the objects & methods you want available for your sites.

It sounds a bit like you have something (call it a McGuffin for any  
film buffs out there) that is installed in the root so that it should  
be available for any lower level item but it should also be  
customisable in some way. Why is this different to default instance  
of the McGuffin installed at root level with local, customised  
McGuffins installed lower down the hierarchy? This is standard way to  
do things in Zope, ie. you can overwrite the document_view method of  
any particular document.
