_getOb and _setOb are for placing subobjects somewhere besides attributes (which is the default implementation).
When would __getattr__ be used then?
In what context? You could wire __getattr__ to call into _getOb (and probably __getitem__ too, since that's also used in traversal and as a way of getting non-Pythonic ID'd objects). def __getattr__(self, attr): return self._getOb(attr) Until very recently, __getattr__ on persistent objects was like playing with nuclear fire. But now, I *believe* it behaves properly, which means __getattr__ gets called when it receives an unknown name. How that affects Acquisition, I don't know.
