Some comments on the code:

Can we get rid of these absolute paths? Something like this should suffice:

>>> from ctypes import *
>>> buf = create_string_buffer(4096)
>>> windll.kernel32.GetSystemDirectoryA(buf, 4096)
17
>>> buf.value.decode("mbcs")
u'C:\\WINNT\\system32'

This also hides typos and whatnot. I guess it's better if each function catches
its own exceptions, and either return None or raise a common exception (like a
class _GetNodeError(RuntimeError)) which is then caught.
