Has the idea of variable stroke width been formalised or considered yet? I suppose there would be different ways of doing it, but I would think that another set of bezier handle(s) at a node could determine width at that node, or additional handles might determine whether the width variation to/from the neighbouring nodes is linear/exponential.

Some others thinking about it: http://www.w3.org/Graphics/SVG/WG/track/issues/2271
