Finally got around to trying this.  chowning does it and makes the 
buttons disappear (shutdown and restart, not end session).  That's kind 
of nice, but the pipe comes back with each session.  Not hard to do 
something that will watch and keep it disabled.

I also (based on Jed's suggestion) removed exec from /sbin/halt, which 
KDM uses to shutdown/reboot.  Then any of the 3 buttons just ends the 
session.

So either way works, just have to educate my users what to expect. 
Thanks for the help.
