I think it's usually more productive to post questions in the discussion forum than as a blog entry...that said, you're going to have a hard time getting a mesh that's both clean and close to your original surface if its edges are curved.  Meshes have to be build along polylines, so any mesh you make from a planar surface with curved edges is going to approximate that edge...and that will result in all of those edges you have right now.  If you use the original voronoi polylines and then something like the "stellate" component from weaverbird with the distance set to zero, you'll have much better meshes.
