Rules are very clear, you need permission to fly commercial drones.
The only drones that can get licence is experimental and military/police drone or somewhere far away in boonies, like Alaska.
There is no commercial permit for drones that most people are interested to get. Like photographing a house for sale. Even Amazon could no get it, all those videos filmed elsewhere.
I would say 3D printers are at the stage where "micro" computers were in early 80's, yes there were big expensive real computers and almost a toy for home use that you often needed to assemble by yourself. Did majority need computer then, no; today, well who doesn't have smartphone.
Look into inflation, before you think it is a modern thing, check 15-16 century http://en.wikipedia.org/wiki/Price_revolution
Simple rise in amount of gold and silver from oversea colonies to Europe caused 6x increase in price over 150 year.
Try Fiasco, no gm, 3 or more players and all characters end in jail, dead or insane. Think of any movie that went terrible wrong, you are playing those characters. There is even a version where you play monsters while Harry Dresden from Dresden Files is hunting you.
Just to make sure if I understand, lets say I film a car, so if I don't film manufacturer logo it is ok, but if I do than I am in trouble? Can actor refer to the car's manufacturer if you don't show logo?
How this type of Intellectual Protection works for books, graphic novels, photography? It looks very murky to me.
Why it is required permission of the manufacturer to show item in the movie? Second if item is going to be destroyed wouldn't it be expected for fake to be used? Is it legally required or "keep court away".
