Medvidovic and Edwards provide in their paper (henceforth referred to as the Roadmap) a technical basis for mobility. They specify the architectural background for software of the future, dividing it into Mobile Software and Mobile Systems. This commentary adds to their work by describing the model of a higher-level application area that builds on top of their architecture.Computer Supported Cooperative Work (CSCW) provides technology that supports collaboration amongst co-workers and group members. With the advent of wireless and mobile Internet communication technologies, research for CSCW has focused on providing access, anytime and anywhere. Frequently, the collaborators are casually connected via the Internet and do not have explicit control or knowledge over the environment. We discuss a conceptual model that can be used to distinguish casually connected collaboration from other kinds, and we identify its architectural requirements. Our model refers more to the second part of the Roadmap, that on Mobile Systems.There, the major issues identified are scalability, heterogeneity and trustworthiness. Not all CSCW systems have these as their only challenges. We describe a model with more criteria than the Roadmap, each with a range of values.
