Limit login to one session per user only

[calce]

It'd be nice to have an option that limit a user to have one session only, e.g. logouts all other same user's sessions and keep only the newest logged in one. This is good for game apps.

not sure i understand - you saying if they have sessions in other browsers that may or may not be open right now, log me out of those browsers when I log in to this current browser? Not sure I'd know how to do that, to be honest

Yes, exactly.

I know it's not easy, I'm trying to find a work around that.
