Not only in principle, but also in practice, as I stated earlier. I 
would suggest having a look at "man pam_console", which is the way this 
kind of stuff is currently implemented.

There is no concept of more than one "local", i.e. console, user in 
Linux (or any other OS that I know of, for that matter), and changing 
that would be quite some work. Except for obscure vintage machines, does 
computers with more than one direct-attached keyboard even exist??

Anyway, in Linux, PAM is usually what (automatically) provides the 
mapping between session and privileges. You could add your own PAM 
module to associate the necessary privileges with a user session based 
on whatever parameters you want.
