Content sharing via the Internet is a widespread means for people to foster their relationships irrespective of physical distance. While network-based social applications are essential to overcome distances and connect people around the world, relying on infrastructure services for location-aware services may often not be desirable. In this paper, the authors propose and analyze a fully distributed variant of an ephemeral content sharing service, solely dependent on the mobile devices in the vicinity using principles of opportunistic networking. The net result is a best effort service for floating content in which: information dissemination is geographically limited; the lifetime and spreading of information depends on interested nodes being available; traffic can only be created and caused locally; and content can only be added, but not deleted.
