Barry,
As Colin said - you do not have to provide them with root access - nor should
you do so! What happens if, for instance, they do
rm -R /
(Hint: do NOT try it on a system you care about!).
Backups I understand. But IP address changes? Why would those need to be done?
Static IP's are generally set up at install time, dynamic ones are handled
automatically. In either case, you don't need root access.
Check some of the Unix groups for more information on security.
As for encoding - they will stop the casual peeker. But they won't stop someone
who really wants to get at the code. But then if they really want it, even
compiled code (i.e. C/C++) can be gotten at.
It's just a matter of how much effort they're willing to expend.
