This paper deals with computer supported cooperative work in the context of untethered scenarios typical of mobile environments. The scenario envisions a number of homogeneous peers that are able to provide the same services, disconnect frequently from the net, and perform part of their work while disconnected. The application we choose is Configuration Management (CM), a critical cooperative activity occurring in software development. We discuss an implementation of a configuration management tool in a peer-to-peer setting, evaluate our solution with respect to other systems, and draw conclusions for future development.
