I don't actually require what I am about to ask, I am just interested to know if such a system exists. The majority of my experience is with Windows based computers.
Are there any operating systems that allow you to pass a session of applications etc to another user.
Here's the scenario;
A user has x number of apps running on a computer, they want to go home or go somewhere else, and they just pass the entire session over to another user, and the applications continue to run, but under the other users credentials.
Does such a system exist? Perhaps this is how mainframes work?
