Filemon-ish behavior by Python?

Glancing at the filemon blurb on the sysinternals website, they describe
its operation as follows:
"On Windows NT the heart of FileMon is a file system driver 
that creates and attaches filter device objects to target 
file system device objects so that FileMon will see all 
IRPs and FastIO requests directed at drives"

It might be possible to do this in Python using ctypes
and -- from my experience -- many hours of toil and sweat
oscillating between the MSDN documentation, other peoples'
examples, and the ctypes data structures. (Altho' I defer
to the many millions of people better qualified than I am
to determine this) But could I just ask: do you want
exactly what filemon is showing, or do you have a
slightly different requirement which filemon happens to
satisfy? It occurs to me that if you were just after, say,
audit logging, or noting file changes or something else,
then it might be possible to employ some other approach.
