CORBA Callbacks

Let's say you've been pestering your Aunt Fran about the details for her latest wedding. You call her every day, and she is getting sick of it. Finally, she tells you that she will call you "only when something happens."

In essence, the two of you are setting up callbacks between one another. When Aunt Fran gets an event that you should be aware of, you will get a call. Otherwise, her phone will be silent, and she will not be bothered.
