This paper suggests a relationship model for describing, analyzing and foreseeing conflicts of interest in file-sharing networks. The model includes levels of relationship ranging from the individual (ego), to the small group of close peers (micro), to a larger network of acquaintances (meso) to the anonymous larger network (macro). It is argued that an important focal point for analysis of cooperation and conflict is situated in the relations between these levels. Three examples of conflicts from a studied file-sharing network are presented. Finally, the relationship model is discussed in terms of applicability to other domains, recreational as well as professional.
