MrIntelligentDesign has no cause to avoid the question of how to tell the difference between a natural object and a manufactured one. William Dembski answered that question ages ago: specified complexity. You can always tell a manufactured object because it has specified complexity. AZPaul3 alluded to this indirectly in Message 4.
Once MrIntelligentDesign adds a few sentences on specified complexity to his paper, it should be well on its way into the pages of Nature.
