I believe Windows NT has the ability to turn on/off auditing on a
per file basis.  It would be nice if you could provide for getting
details like the uid who opened the file, a timestamp, open flags,
denied open requests and other miscellaneous details like that if
possible so someone later can write fauditlogd. (file audit log
daemon)  I wouldn't personally find it useful, but I'm sure someone
else would.  (And I can't resist suggesting ideas for others to
implement ;))

It would be nice to be able to put in wildcard ``callbacks'' too,
although perhaps this would introduce too much of a performance
penalty.

Do you have any idea how much overhead the system would have on
normal files for which no ``callbacks'' have been installed?

Sounds pretty cool.

Niall
