The fbtab/tty_relatives/tty_action/whatever being discussed is not about
authentication/authorization. It's run AFTER the user is validated for
login, which is too late to do anything useful. I agree with Gordon
here; don't try to jam additional functionality here where it doesn't
belong. I already have plans for a separate mechanism to handle the
other things.

Again, it's too late. You don't want to say "no, don't let them login"
after they're already been validated. You want to do that beforehand,
and in fact you want the mechanism to control not only if they're
validated, but _how_.
