+1 for that, if it is doable, I didn't investigate it further than the comment's claim that it is too difficult. I didn't want to say that I think it is a real-usable scenario, I meant valid as currently reachable (as showcased by the isolation tester spec I posted), that probably wasn't the best word to describe it.
