I don't think anyone should rely on wtmp for any kind of security.
Whatof rsh? Its easy enough to do a rsh <host> xterm -ut -display <foo>
and avoid wtmp detection. The -ut flag tells xterm to not make a
entry in utmp and it never considers making a wtmp entry. I suppose
because it never has permissions to. The rsh server would have to
make the wtmp entry. Which is odd it doesn't because it does if
envoke a shell with it. Hmmmm...
