Good work digging up that bit of info. I was curious about that serial number as well. I guess I didn't think it would be anything that mundane.
Although, somehow I doubt that The Cleaner will keep out any trojans planted by our intel agencies. :)
My first thought was that he was giving the serial number of a missing nuke or something to prove that they had something. I looked again and noticed it was hexadecimal which is a common format for software serial/keycodes.
