"To oversimplify it," Skater said, "an encoding in the delta-ware is sort of like a maglock. If you have the key to that maglock, you can get in. If you have a key to another maglock, you can’t. The major corps—Fuchi, Aztechnology, Saeder-Krapp, etcetera—use archived programming in the deltaware only at the top levels of their ops to keep access to those areas down even among different divisions. Caber would have been a good candidate for that because of the espionage ops he was involved with."
