pg_space_cadet

pg_space_cadet is a simple hack for postgreSQL and ActiveRecord which provides a uuids table of distributable identities of space cadets -- ActiveRecord::Base instances which use the SpaceCadetWrapper. Each space cadet has a default ActiveRecord id unique in the set of all local space cadets; a space cadet's id is derived from its uuid - UUID's are by design universally distributable.
