"Circular Multilateral Barter" (CMB) is free server-side software for managing peer-to-peer networks for circular barter exchange. CMB advances conventional barter by making it multilateral. It does so by engaging peers' trust to decouple the actual delivery of goods from the agreement to deliver the goods.
