One thing I do is to edit my sudoers file on a workstations that only 
"sudo admins" have access to.  When the edits are done, a script is run 
  to push the modified sudoers file to all the machines that use it. 
This script also writes out a file with the new sudoers file md5sum in 
it.  A cron job run regularly that checks the md5sum for suders on all 
of the machine and it if there is difference, notifies the sudo admins.
