Shares a server-wide object associated with the specified name over the specified
 channel.  All connections with RMI hosting started will have access to this shared 
 object as soon as they connect, and they will all share the same instance.  It is up
 to the shared object to handle any multithreading that might be required.
 All network communication associated with the shared object will be done over
 the specified channel.
