I use MoI to create high quality and light meshes for rendering. MoI helped me often to get projects with complex models be done. :)
Also the MoI mesher could help to create light clean models for 3D PDF creation per simlab rhino plugin.

My biggest problem is, that I can't mesh all NURBS objects of a scene and the layers are keeped (best also the material names). If the meshes could be written to a 3dm file too, than this should be easy possible. Or could you enable 3dm mesh export without to think about the question of meshes in MoI?
