Missed naming opportunity...

                    No, no, I'm sure, but -- you understand.
                    It should only be a couple of days.
                    What's the thing you're working on?

                    It's called Tron. It's a security
                    program itself, actually. Monitors
                    all the contacts between our system
                    and other systems... If it finds
                    anything going on that's not scheduled,
                    it shuts it down. I sent you a memo
                    on it.

                    Mmm. Part of the Master Control Program?

                    No, it'll run independently.
                    It can watchdog the MCP as well.
