A store of interfaced software objects are distributed between a server computer and multiple client computers to support an object oriented application communication environment that provides communication between software applications on each client computer. The application communication environment may include a central shared object store of interfaced software objects that operate on a server computer and communicate with one or more software applications on the server computer. A local shared object store of interfaced software objects operates on each client computer and communicates with the central shared object store and one or more software applications on that client computer. Changes to interfaced software objects in the local shared object stores may be automatically propagated to the interfaced software objects in the central shared object store. A local private object store of interfaced software objects may operate on a client computer and communicate with one or more software applications on the client computer.
