Several DS simulator exist in literature. If you're used to Java: peersim.sourceforge.net. SPLAY is another good example: splay-project.org – Valerio Schiavoni Dec 19 '11 at 10:28

In other words, when does distributed labor become so specialized, that a black-swan type of event would topple such a system and necessitate a more resilient, although redundant, system. For instance is their a good formula to determine if everyone should grow their own food and only work part-time at another job, or should they devote full-time to a job and let someone else specialize and grow food. – EhevuTov Oct 8 '11 at 7:23
