/**
 * The ServerProxy class implements the IServer
 * interface and represents a client's local proxy to a remote server.
 * This object is used to talk with the server.
 * 

 * Note: This class/interface is part of an interim API that is still under 
 * development and expected to change significantly before reaching stability. 
 * It is being made available at this early stage to solicit feedback from pioneering 
 * adopters on the understanding that any code that uses this API will almost 
 * certainly be broken (repeatedly) as the API evolves.
