I was wondering if it's at all possible for one to write a program that, when you run it, allows you to APPEAR to be doing one thing, while you're doing something else. Not quite like a Trojan horse, but a bit similar. What I have is, a character has written a program to use during work that, when opened, allows him to surf the internet, while to his superiors' eyes his computer appears to be doing some other mundane thing that is not surfing the Internet. The computers at his job are always connected to the internet, btw. I seem to recall from high school that our tech people said they could monitor our internet useage from their own computers, but they never actually said how.
Anyway, I was just wondering if the idea is feasible. It's not THAT integral to the story, but it's an Important Little Detail.
edit Lovely, I've got what I need. Thanks, guys!
