We should have an ITraverser for IObjectManager and for ISimpleItem. The 
one for IObjectManager should be modelled after 
zope.app.container.traversal.IContainerTraverser. The one for 
ISimpleItem would be the DefaultTraverser. Alternatively, it could be 
registered for *.

Maybe OFS.ObjectManager instead of OFS.Folder?

I still suggest browser:resourcesFromDirectory.
