Describe the necessary modifications to the Task Bag interface to allow callbacks to be used.
What will be an ideal response?
The server must allow each client to register its interest in receiving callbacks and possibly also deregister. These operations may be added to the TaskBag interface or to a separate interface implemented by the server.
```
int register (in TaskBagCallback callback);
void deregister (in int callbackId);
```
