	Running multiple X servers is easy enough - I used to do it quite a
lot using startx, you just have to give each one a different display
number, as long as there's a spare virtual console X will pick one and use
it. You switch between them with Ctrl-Alt-Fn as normal.

	That doesn't secure the sessions though. For that the user switcher
has to lock the current session and switch to the selected locked session
or create a new one - and of course something has to disable normal virtual
console switching to prevent leaving unlocked sessions lying around.
