While reading through another thread I got an idea.
What if instead of having a host with a driver with a set resistance we just wired the driver board to a 2.5mm headphone jack at the solder points for the resistor/pot. We could then wire the resistor to the plug. This way we could have multiple outputs and driver would not work without it and this would function as a interlock at the same time. Maybe we could even find a more proprietary plug to avoid someone trying to put in a mini headphone jack (even though that shouldn't complete a circuit anyway). Has someone tried this?
Forgive my run-on sentence.
