1. A method for routing asynchronous state changes in a multi-processing system having an end user system, a central application server system and an endpoint system, the method comprising:

  • detecting a state change with a service object on the endpoint system;

    sending a notification to an associated service proxy object on the central application server system notifying the associated service proxy object of the state change;

    sending a notification to an associated distributed service object which is an owner of the service proxy notifying the associated distributed service object of the state change;

    sending a notification to an associated distributed service proxy object on the end user system notifying the associated distributed service proxy object of the state change; and

    posting an event to an associated owner window of the distributed service proxy object using a window identifier including sending a notification to the associated owner window notifying the associated owner window of the state change.
