Sure, just make 'mount' set-uid root :-}.

No, I only go to UCSC to ride off-road. The 'no biscuit' line is from an old "Far Side" cartoon (guy at his front door says to his dog, while looking out at a lawn that shows evidence of very sloppy mowing: "You call that mowing the lawn? Bad dog. No biscuit". I do miss it...).
