Can I remove the "Log Out" item from the Apple menu?
I've been looking at removing the Sleep and Shut Down options from the Apple Menu on our lab Macs. My focus was OS X 10.7.3. 

I found that just removing the objects, as Daniel Lawson has suggested, also caused the Apple menu to crash when I clicked it.

After closer examination, I noticed that there were references to the Shut Down and Sleep objects elsewhere in the objects.xib file. After I removed both the objects and the references, the Apple menu behaved as expected, and did not show the Shut Down and Sleep options.

Here are my changes to the 10.7.3 objects.xib file:
