The pedals thing is a bit of a rub over here. I currently don't run em on my rigid but it can and had been a deciding factor for the law. You can get away with a lot of shit if you can prove that your bike can be pedaled.
I agree with you to a point with the secrecy thing. Yet just because I don't share now dose not mean I will not share when I have proof of concept in hand. When I know something works it is always posted so fellow mopeders can utilize it. I just like to get the kinks out first.
When it comes to stuff I'm working on in my garage I will give advice and info on threads that have the same questions I am trying to answer. But like to work things through from start to finish on my own.
