As far as I know provideAdapter treats None the same way as Interface. I've used this pattern a few times: from zope.adapter import adapts, provideAdapter from zope.interface import implements ... class SomeAdapter(object): adapts(None) implements(IFoo) ... provideAdapter(SomeAdapter) BTW passing interfaces to provideAdapter/<adapts> is out of fashion. I prefer using zope.component.adapts and zope.interface.implements (or zope.component.adapter and zope.interface.implementer, when my adapter is a function rather than a class).
