Hi Rudl - it's actually kind of the opposite of that which would be helpful - having the vertex normal data read in from an OBJ file (currently it is just skipped), and preserved along with the model.

When MoI writes an OBJ file, it writes vertex normals which come from the original NURBS surface, so they basically represent the ideal shading. When blender recalculates them, it does not have the original NURBS data available to it, it only has polygons.
