I suppose this is no Life game > at all, but some kind of zip/compress utility This is just Brin taking liberties with the narrative. To make Life reversible would require enough changes to the system that it wouldn't be recognizeable as Life anymore. The reason you can't use a Life grid as a form of encryption is that you can't reverse the process. Brin takes many liberties with Life in the book. Gliders do not bounce off of walls or artificial boundaries (borders). etc.
