Back in the late 1980s I tossed this idea around while I was in college, and had it scoffed at by various faculty members. Part of why I decided to drop out.
Users ID'ed through typing, mouse movements:
A series of 90 minute typing tests carried out on 2000 people at Iowa State University found users could be identified with a half percent margin of error based on the way they hit keys.

Not positive, but I strongly suspect you would need multiple profiles. Hungover Dave doesn't type
the same as Sleepy Dave, who doesn't type the same as well-rested Dave, who doesn't type the
same as over-caffeinated Dave.

Got to thinking about this, and realized that one of the problems with customizable interfaces is that when someone new takes overmy computer for a short time, they get completely confused. What if my EDITOR environment variable could tell if I'm the current active user and give me Emacs with my ~/.emacs.d/init.el, but offer Charlene gedit?
What if, when we're driving and someone calls or I want to use the phone for nav and I hand my phone to her and say "can you...", it gives her something more approximating the default, or even her interface, than my customized one?
