I believe we are in a better position to understand the principles involved with electrical safety. And if we don't know the answer, we have better background knowledge to read up and find out. Maybe we have more of an idea where we should look, what gaps are in our knowledge and a better understanding of what issues may arise. I stress that we only advise and I have aired on the side of caution with my last comments.
ValleyLab have equipment that can operate in this manner. And as far as I'm aware it's two floating generators, without any linking between the two I can't see how any clever circuitry could possible overcome different potentials between two floating generators.
I say put the ball in the court of the manufactures, not I don't have the ability to comprehend the issues involved!
