Some interesting notes: professional font designers regularly copy each other's work. However, if you ask a legitimate font designer, they will trace another font. Where they get in hot water is if they copy and/or manipulate the actual Bezier points from another file (at which point they are copying the code). I remember going to a font design conference a long time ago, and some elite well known designers were aghast at another well known font designer for copying the bezier points directly off of another font and then manipulating the points from there. It's a crazy little dance they do to keep things legit.
