Very Interesting thread. In this case I'd like to introduce you to a new slang term used for many years called "shoulder surfers!". Though this term has a newer meaning these days, however the concept of this term goes back to school days. Almost everyone who is creative is exposed to the issues being listed on this thread. On ideas, it is always pretty tricky to want to find someone to trust who can help you/partner with you because it is just an idea that can be shaped very easily into something else. It is worse when you have build the idea and discover that others have been trailing waiting to use you as an experiment on the failure/success on similar avenues. There are many who play the vulture game of sit and wait, pounce when ready. How to protect one's ideas or originality is quite a difficult one. All I can say is "been there and been taken for many rides". Going back to the early 90's when car alarms did not have any advanced features like anti-car jacking etc I once met one alarm vendor whose idea it was to develop such a system. I successfully created a vehicle seat activated system with a passenger seat bypass, after many months of tinkering with microprocessors and timers. I handed over the prototype to the guy who said it would be cheaper to produce in china etc. I never saw it again but do remember seeing similar devices being sold off the shelf on similar concepts with fuel cut-off valves a few months down. The vultures, trolls and shoulder surfers are around you. How to protect your ideas/concepts/projects is almost impossible. Me thots.
