Well, this is not meant to protect you from people in the same room, for 
that there is your password. It's meant to protect you from worms. The 
sudo program can become root to read such a file and present it. And no 
standard executable can do that because you need the setuid bit. But I'd 
prefer somebody with experience in security talk about this.

It's not offtopic in my opinion as exactly this machinery could be used 
in the infamous popup to address the concern of many, but can be moved 
elsewhere or dropped if it has obvious flaws that I don't see.
