fiore@0:  * This comes handy for eventual further implementations of a network-based real time sharing system. So 
fiore@0:  * the network client can implement this interface and, instead of directly changing the diagram, it can send 
fiore@0:  * messages to a server and change it accordingly to the server reply.
fiore@0:  * All in a transparent way to the classes which are in charge of editing the diagram.
