It is a local hack, but actually was Fred Blonder's idea.

Since /bin/login applies the restriction, there is no way for anyone
to circumvent it except via `su' (or other setuid programs, possibly
setuid to that person).  The latter is not worth protecting against
(too difficult, for too little gain).
