Most insightful part is the forward thinking about the new wave of enforcement that copyright infringement of physical goods via 3D printers will bring. Something I hadn't considered before, but a massive shift indeed.
Chicago Public Library just recently opened a 3D printing lab, complete with free lessons and a variety of tools to go along with the printers. I have a feeling that it's going to be successful and it's going to garner more interest as time goes on. So yea, there are a couple of industries that are pretty scared right now.
These cases seem comparatively insignificant to me. I think patent infringement will be the real "intellectual property" issue with 3D printing. I'm looking forward to a renewed debate on the ethics of having governments intrude in people's private lives to enforce corporate monopolies.
