I agree that the inverted mesh method doesn't always look good but alot of that depends on how the mesh is created in the first place. Convex shapes with no overlapping polys will give you good results.
If the method you're going to use involved drawing lines over the top of the mesh ... surely they'll need to be a decent thickness to have the desired effect?
