Abstract: A diversified processing system and associated method are disclosed for updating at least one remote computer platform with an action occurring on a local computer platform. The disclosed system and method minimizes the amount of locally generated information that needs to be transferred across a network so as to maintain on a remote computer platform a copy of what has occurred locally. To minimize the information sent between platforms, each platform may contain items, referred to as instances, which respond to various types of commands. The types of instances include master, proxy, and free instances. Master instances and proxy instances relate to the same item located on different platforms. Each master instance keeps its related proxy instances current with its status by transmitting its changes between platforms to its related proxy instances. Free instances respond to changes occurring preferably on a single platform.
