Oh yea the techie side is certainly a challenge. Though I like CyberDream's point about EULA's. Citing copyright, supermarkets bakers already refuse to print photos on kids birthday cakes if the kid is wearing a football shirt or dressed as something like scobby doo. Highstreet photo kiosks, and sometimes the staff, ask if the work to be printed is professional. Which for me often is, and I've been asked a few times to prove it's my work or if I'm a pro. While thats easy to confirm, in future will 3D printers ask us to prove we own something before printing it? If so where does that leave things like fan-arts?

Pinky - you left the lens cap of your mind on again.
