[Zope] How to make a folder with a path property?

Dear List We are trying to make a folder-like product with a path property. In one of the zope books it says that __bobo__traverse can be used to let an object have multiple parents. CMF has the skin_tool and in some sense one could say that what we want to make is a product where there is only *one* skin. Should we use is the bobo approach or the CMF way? \Oliver
