If the spline is too curvy and distance between two shape segments is too short, segments will overlap and as a result the mesh looks ugly. So (at least in theory out of my head) handling this is a two step process: Detecting overlapping segments and resolving it.
Detecting isn't hard, basically Plane-Plane and Line-Line intersections. Solving that may be harder. Either welding vertices or repositioning them in a clever way might solve the problem.
I may be totally wrong and I didn't tried it yet. If you've got a great idea, let me know.
Aaah now I get what you mean by sharp edges. I was thinking of sharp edges in a sense of shading (you know smooth shading vs flat shading). But you're talking about sharp edges in curves! That sounds considerably less easy to solve indeed.
