Interacting with knowledge in a timely fashion is critical for the
success of humanitarian missions. At the same time, the places
where humanitarian action is needed are often those where Internet
connection is poor or not available at all, making digital
knowledge access difficult. In this paper, we propose a novel knowledge
delivery model that relies on a peer-to-peer middleware and
uses low-cost computers for local knowledge replication. We have
developed a system implementing the model and evaluated it during
eight deployments in Médecins Sans Frontières missions. The
evaluation demonstrated knowledge delivery abilities of the system
and its usefulness for the field staff.
