24      * new instance on the server. <p/>2. The instance on the server creates a new proxy to another
25      * specific instance on and sends this proxy to the client. The client then have access to this
26      * specific instance. (Proxy created on the server-side using:
27      * <code>RemoteProxy proxy = RemoteProxy.createServerProxy(myInstance, "localhost", 7777);</code>)
