...but how to execute?

I would bring this to MJFF or APDA, PDF, NPF or one of these organizations. Of course, it would be a monumental (if not impossible) task for you to take on yourself. Only these organizations have the money, knowledge and power to put this in motion.

It's a great idea, a solution to a problem we have all worried about from time to time, and one that should be brought up with these PD org's.

Thanks for thinking so constructively on this one!
