> How does one receive notifications from 10.8's new system-wide Notification Center? Is there a framework that allows a Cocoa program to receive system notifications, i.e., the ones that show automatically in the upper right hand of the screen?

No, it’s the other way around — Notification Center is for apps to _send_ notifications to, not receive them. The notifications are purely for the user to see.

There are several existing mechanisms like NSDistributedNotification, NSWorkspace and kqueues for getting programmatic notifications of things outside your process. Is there something specific you want to be notified of?
