Yes what you're proposing would be useful, if it is really really simple. I think it'd be a useful teaching tool, for people who want to learn file systems w/o the huge overhead of a fully-featured f/s. I would suggest you consider the msdosfs sources, being that they are probably the simplest, and remove much of the code to make it, say, use a limited number of dirs and files. Erez.
