you can do it by using listeners, something that is widely used in
GNOME.

For instance, you could have:

interface Server {
	void connectClient (in Client client);
};

interface Client {
	void notify (...);
};

and have the Client interface be implemented in the client-side, so that
it can receive notifications from the server.
