. In this paper we describe an application model for seamless mobile data access using handheld devices and wireless links. We go beyond the current model in which handhelds are used as smart organizers augmented with stripped down versions of popular desktop programs. Instead, we propose to integrate handheld devices seamlessly in a distributed computing environment. Componentized applications, adaptable middleware frameworks, and standardized protocols play a signicant role in this new paradigm. We also describe an implementation within this paradigm using PalmORB, a CORBA client for the 3Com Palm devices. 1 Introduction The current distributed system organization is machine centric. Users have different accounts, passwords, and software on dierent machines. This organization has suÆced for the computers to users ratio of one or less. However, with a larger computers to users ratio, aorded by smaller devices and cheap wireless connectivity, the existing model breaks down. The cha...
