  abstract =	 {The BitTorrent file distribution system uses
                  tit-fortat as a method of seeking pareto
                  efficiency. It achieves a higher level of robustness
                  and resource utilization than any currently known
                  cooperative technique. We explain what BitTorrent
                  does, and how economic methods are used to achieve
                  that goal.},
