OK, I wanted to do a few more, so I built Processes and Notification, too. Processes seems to work fine (once again, modulo the file spec issues); I can print out most of the information about each process (including PSN, but not yet the path), and I can launch an application by its full path.
And the notification thing is cool; I can bring up a dialog window with a notification message. I can get it to beep, too, but for some reason it won't play a sound from a resource right now. Oh well.
