Greg,

I've been thinking of how to solve this particular problem, and believe
you could use dnotify in a daemon to track permission and ownership
changes and store them in a backing database. In fact, we do something
similiar to this today. This allows the user to use any type of
application for changing permissions/owners, even syscalls directly
without having to go "through" any sort of tracking database.
