Unless you are a service provider dealing with issues such as activation, lifetime management, or transactions, you do not need to distinguish between proxy references and object references. The remoting infrastructure uses transparent proxies that give the impression that the remote objects reside in the client's space. Proxies achieve this by forwarding calls made on them to the real objects at remote locations.
