Support for distributed CSCW applications

This chapter reports on advances made in the field of distributed systems t echnology for the computational support of CSCW applications, with emphasis on distributed synchronised applications (i.e. same time, different place) . The main concepts are first recalled, and illustrated by the description of two CSCW platforms developed in Broadcast: NAVCOOP, based on a group-ori ented communication layer, and CoopScan, based on software agents. Finally, the techniques for enhancing a legacy interactive application with facilit ies for distributed cooperation are discussed and illustrated by two exampl es.
