Function: The NSDistributedNotificationCenter class provides a way to send notifications to objects in other tasks.
Notes:
It takes NSNotification objects and broadcasts them to any objects in other tasks that have registered for the notification with their task's default distributed notification center.

The NSDistributedNotificationCenter class implements a notification center that can distribute notifications asynchronously to tasks other than the one in which the notification was posted. An instance of this class are known as a distributed notification center.

Each task has a default distributed notification center that you access with the defaultCenter class method. There may be different types of distributed notification centers. Currently there is a single type—NSLocalNotificationCenterType. This type of distributed notification center handles notifications that can be sent between tasks on a single computer. For communication between tasks on different computers, use Distributed Objects Programming Topics.

Posting a distributed notification is an expensive operation. The notification gets sent to a system-wide server that distributes it to all the tasks that have objects registered for distributed notifications. The latency between posting the notification and the notification's arrival in another task is unbounded. In fact, when too many notifications are posted and the server's queue fills up, notifications may be dropped.
