I haven't heard about anyone doing this.  You could modify
the VFS to notify you everytime a file is created, moved or deleted.
That should give you what you want, but at the cost of delaying
those operations.

Another option would be to make a filesystem that stores its
directory structure (or a copy of it) in a single file, so that
a locate-like program can do quick lookups of the always-correct
data.
