The problem I face, is that this "magic" (sorry, company policies prevent me from being more specific than that) may cause some files to disappear and new files to appear. And the end users do not appreciate having to press F5 between file operations.

FYI: This is fine (proprietary VFS) if used within the company, but must be
released as GPL if you redistribute this functionality outside the company.

If the client has a change notify request pending on that directory you can respond to
it and the client will then refresh the directory listing.
