No, but another idea comes to mind - what sort of file is it? If it is a text file, and it is changed by a human operator, could you roll a wrapper for their editor that will perform the necessary actions upon save and exit? This way, no need for an additional external script at all. Even if it is copied from the network, something similar would be possible, I'm sure. Just a thought.
