was also wondering if anyone ever think to encrypt their NSNotification data?
If you start getting to that point, you should think about using a real IPC mechanism instead. NSDistributedNotifications are very easy to use, but they're intended as one-to-many notifications, not for two specific processes to communicate. I mean, they work for that, but they're very limited in what you can send, and as you point out, there's no privacy.
You can send point-to-point messages between two processes using direct messages between Mach ports. I believe the huge "daemons and agents" technote has pointers on doing this, and there are also some sample apps demonstrating Mach messaging.
