I'm curious if this would one day allow human muscle tissue to be sold. I saw this weird movie where most, if not all diseases were cured, and there was a obsession with celebrities. If they got a virus, it would be sold at a high price. And their vat grown muscle tissue was sold at a local deli.
Only connect one data link and ground, and it will be secure. Run a balanced pair if you are feeling fancy. If the receiver can keep up, you don't even need flow control lines. Problem solved.
You could just set a led that blinks when there is something wrong and have a 2 dollar webcam monitor it. If someone manages to force data through a led that isn't configured for such activity, they have won the internet and deserve access.
