Microsoft is banking on enhancements to what it has dubbed the fundamentals to entice enterprises to upgrade to the next version of Windows, known as Vista. The company will use upcoming industry shows to sing the praises of improvements to the Windows networking stack and secure networking techniques such as server and domain isolation to sell both Vista and Longhorn, the planned update to Windows Server.

What it really needs is a way to restart the X login manager that does not involve zapping the entire X server. That would allow the kind of security you want (you can ensure you really are logging into kdm or gdm and not someone else's trojan they left running), while at the same time protecting remote X application users from having someone pull the X server out from under them like Ctrl-Alt-Backspace would do.

It can't be trapped because it is not an OS signal like SIGINT (Ctrl-C) is. It can be disabled in the X config file with the "DontZap" option. That does require root access of course, but many public terminals (such as those in University computer labs) do have the DontZap option in the X config file because they don't want normal users to be able to kill the X server (which would be rather nasty if remote users were using X applications on that system.)
