Answer 1

Amit Singh discusses these undocumented APIs in this online bonus chapter, but does so using C -- I'm not sure if a Python extension exists to do the same work from Python, perhaps as part of PyObjC (otherwise, such an extension would have to be written -- or ctypes used to access the shared C libraries directly from Python [shudder;-)]).
