In the parlance of information security, the term "Separation of Duties" describes a mechanism for ensuring security. This is how it works: You train each monkey to perform one simple but different task of the whole process, so that no one monkey know how the whole thing works.... unless they learn how to cooperate and share information which is very unlikely in less-evolved primates where greed and individualism dominate.
Terra Tech monkeys are smarter than the average monkey. I heard some even attended The Wharton School of Business!! Someone else attened there but their name escpaes me right now. ;-)
