Delivering packages using the social network

PeerPost is a web application that enables users to build a social delivery network and use this to send small packages. It makes use of the fact that many people take the same routes and meet the same people every day. Members provide a list of people they meet most days plus a timeframe for each person or group of people. For each delivery, PeerPost selects a chain of people, and tells each person who is the next in the chain.
