When I quit screen, I don't really "quit". I just detach from it. I 
usually either do a ctrl-a d as you said, or I just close the xterm 
because I'm almost always in XWindow. Screen does have the ability to 
alter keys, so you can turn that feature off. I use screen as an 
ameteur, so basically it's features are completely unused by me other 
than detaching and naming. I do know that the ctrl features are 
alterable with screen, though.

Having a primary console via screen is all well and good, but having a 
serial console is probably the better way to go for less vulnerability 
when it comes to what a user does. (such as quitting screen, as you said 
above) That's what I'm suggesting. Perhaps having a a serial console 
available for the user, instead of giving them direct access to the 
primary "screen" session.
