What you're talking about is called kiosk mode, and there's
compromises no matter how you go around it, but if you're intending
the software for use in an instructional environment where other use
of the computer shouldn't be vital while your app is running, then the
impact shouldn't be an issue.
There are several ways to do this, and to get started, I'd recommend
reading this apple article. It's geared towards carbon, but parts of
it can be applied to cocoa as well, take a look: http://developer.apple.com/technotes/tn2002/tn2062.html#Section3
Also, here's something from cocoadevcentral that may be of help:

Good luck!

Hi All,
How can I lock user screen (using cocoa+objC) that just a quote
appears at
screen and user can not use their machine until my software unlocks
the
screen.
You might find it rude but that is required as we are developing a
training
room software and the trainer should we able to lock all student
screens so
that student can just concentrate on trainingroom black/whiteboard.
Lanuching user machine screen saver wont do as the students might
unlock the
screen saver by entering password. Is there a way that I can create a
screen saver with a random password (not known to students).
Thanks in advance.
