Speaking of facts, here you go: Lucasfilm moves - without exception - against anyone or any organization who crosses into their ever-changing definition of how much illegal money you can make on their stuff. I've seen it happen from both sides, with props, costumes, toys... tons of stuff. They watch, and they know; that should be no surprise. If you make a big enough spectacle of yourself, they will shut you down and it will hurt. You never know where the line is; some days they feel like being more strict, other days they let it slide. I knew a guy who was casting stormtrooper armor from screen used armor, and doing just fine for himself when he was selling a couple dozen or so a year. Then he bumped it up to something like 200, and the shit hit the fan.
The X0 project is near and dear to my heart, philosophy-wise, but I wouldn't want to be them when the music stops. If you believe any differently, you're playing poster boy for selective ignorance. I mean, come ON.
