Not sure if that is the perfect example, you can also run a local user
space nfs server. I think the real difference is 'fusermount' which
typically has the s-bit set and allows mounts from unprivileged users.
I.e. I really think we should differentiate between 
privileged/non-privileged fuse server tasks.
