Not John Carmack, but what about a junior dev? What about the QA people? How far down the chain do you go with who gets to take a copy home?

On a large operation you can't rule out the bitter ex-employee factor either.

If you were a junior programmer at id, would you torrent your work? I doubt it. Leaks nearly always come from outside the company, meaning copies sent to reviewers etc.

If you have a guy working for you who would leak something you're working on, the solution isn't to not allow people to take things home, it's to fire people who would harm your company.
