Architectural design has an important effect on usability, most notably on temporal properties. This paper investigates software architecture options for mobile user-interfaces, in particular those for collaborative systems. One of the new features of mobile systems as compared with fixed networks is the connection point to the physical network, the point of presence (PoP), which forms an additional location for code and data. This allows architectures that bring computation closer to the users

Keywords: mobile computing, collaborative work, CSCW, software architecture, active networks, client-server to the PoP to allow the clients to communicate with the PoP -the PoP therefore assumes the role of server. 3(b) peer-peer communication Direct communication using local communication (e.g. infrared). The shared data is at the client end.
