There is this neat tool, FAM (File Alteration Monitor) for which it exists an old module, SGI::FAM. However, FAM won't work on all systems; IRIX and Linux for sure, FreeBSD if I recall correctly, Win32 surely not.
However, I wonder if this would be a viable solution to monitor a whole filesystem; this sort of stuff works pretty well to monitor a few files or folders, but to monitor everything you'll need some sort of plugin at the VFS level, similar to those used by antivirus softwares.
However if you can accomodate with FAM limitations, it's a nice and efficient tool, and perhaps it deserves a closer look. I suppose the SGI::FAM is IRIX only, may it be easily ported to Linux/others? I don't know...
