Super-hidden computer virus piggybacking idea

I had a really great thought about a super-hidden computer virus piggybacking, like on StuxNet, that could do some serious world-changing damage by... but then I thought, wow, I wonder if somebody did that, and if so, I probably don't want to talk about it. But it was a really great thought.

Now I must away so I can awaken in a future time, to coffee. And seven hungry critters. My little 20-sec video "[TFG] admits: Yes We Can't" in the nic.

Good night, Gracies.
