I only play one on TV, so to speak. The co-moderator of the copyright forum (with Mehndi) is actually a lawyer who really has a much better grasp on the law. All this stuff can get really ugly as you start running into both the computer copyright law and the visual copyright law. Most (or all) of the useful non-lawyer accessible stuff on copyright is for written works, which doesn't necessarily work the same as visual or computer stuff. And then you also have the contracts, which for Daz3D is something like 14 paragraphs of contractese. . . .
