Add an additional back and shoulder joint. For a basic rig, within the current structure, it would solve the specific problem. And since everyone wants basic rigs instead of the more developed ones that should and could be used, it solves the essential problem. Easy? No. Would it piss off clothing makers? Yes -- but no more so than the ERC morphs in the mil figures. In the most ideal of worlds, they would create a new rigging system that avoids the complexities of the weight mapped system and the imprecision of the bone system, while blending the musclularity approach of the weight mapped methodology with the simplicity of the bone based system. In either case of that ideal, however, it would essentially destroy the market for accessories as it now stands, and would further the split in applications thereby.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
