Thanks for all of the useful information about sudo.  It works pretty much 
like I hoped.  I'll have to spend a little time studying it and then 
configuring it so that various users can do various tasks.  The example of 
restarting apache was excellent and it got me thinking about how nice it 
would be to have a group of users with permission to do that kind of 
thing.  You can really improve service uptime that way, but you have to be 
able to trust the users not to do bad things.
