Sure...I guess when I hear "time bomb" I think of something that wipes source code or data. Something that alters the bits and bytes. That's the thing that will cause you a world of hurt. What you're talking about is of course totally legit.
Yeah, using that kind of "time bomb" would be ridiculously bad. I've always looked at that as breaking into the premises and manipulating / burning the books.
I sold a piece of software to a local business a few months ago that works on expiring dates. Each payment I get from the owner pushes back the expiration date until I get the full amount, at which point it's theirs forever(it's worth mentioning that so far things are great).
We didn't agree to a contract for the work I did, so I can only hope I don't get screwed over some how in the future. It was my first freelance job though, so I guess there's a lesson to be learned.
