Does that work > as an ordinary user? Yes, within UML for example. I have a little project to imlement a "userloop" filesystem, which works just like "mount -o loop", but you don't need root privs. This is really simple to do with FUSE and UML. I don't think that it's far feched, that in certain situations the user _does_ have the right (and usefulness) to do otherwise privileged filesystem operations.
