Abstract
A distributed computer system is provided with a listener system interposed between the application server and the surface interfaces of the system. The listener system supervises processing of user entered commands and provides substantially simultaneous feedback of system status and progress of the system response to a command to all users. This allows system users to work simultaneously on a common document.
