 This example shows the use of the instance_mode option when exposing a class.
 
+The client will report the id of the object that handled the request.
+The server will print this as well, but will also show exactly when Pyro is
+creating a new instance of your server class.  This makes it more clear in
+situations where Python itself is recycling objects and therefore
+ending up with the same id.
+
 Please make sure a name server is running somewhere first,
 before starting the server and client.
