Yes, it's just tricky since OSes are made to have lots of flexibility and 
features, rather than to keep people from doing things.  But from a security 
standpoint, it should be quite possible to limit what a user can do.  The BIOS 
is the first thing to lock down, so users can't just boot off their own media. 
Then the bootloader, then you have auto-login for the non-privileged user and 
make sure that user can't do anything you don't want.
