Yeah, the recent change really only required a one-line addition (calling mesh.VertPositionsChanged() after modifying the verts).

I added some edgelist generation methods to the MeshType class, so here's an update.  I also integrated a few changes into my included sample script ('pyd_shrinkwrap_test.py').

I also made a few simple changes to your most recently posted script and linked that as an attachment to this message (as usual, just search for 'Spanki' to see the changes).
