I think what poser needs is a true bones/skin system. Perhaps the new system could automatically translate the information from the old JPs to generate this information. This would means essentially, that the skeletal structure of each figure would be more like what you see in higher-end packages, i.e. the elbow is an actual object, to which the forearm is atached and rotates around, with the actual mesh, the skin, stretching more realistically across the surface of it. The may mean, that future poser meshes could have a new skeleton built it, with an actual anatomical bone structure, thus allowing more realistic movement of skin and perhaps eventually, even muscles. Yes, I know that's difficult stuff to find even in the high-end stuff and to do those things it requires a lot of work, but a man can dream, can't he?
