Bert,
I agree completely with all your points. I just cannot see why our legislators are wanting (perhaps soon demanding) that we eprescribe rather than fax. As we all know, the internet is widely vulnerable to hackers, no matter how "Secure". However, a fax is a fax, originating from a fixed point to a fixed point. And, if a wrong number is put in, it only goes to one wrong place, not potentially hundreds of thousands. I like the code suggestion. There could be some set way to add that code to your fax ID, the number that shows the point of origin.
