IMHO the only way there will ever be a final 'word' on anything about who can do what is if its ever 'taken to the mat' and rulings are forced. As a modeller, there are just too many gray areas that need addressed. I mean, lots of models start out as a cube that is extruded and such... so by the roughest definition, that model is a modification of the cube..the cube would belong to the original maker blah blah blah ok, so that's overkill..but you see where this could all end up right? Eventually this kind of thing will be pushed into legality and then there'd be real basis for all the guessing and armchair lawyers out there to say 'you can do this' or 'you cant do that' :) BT
