the problem with rsh is it doesn't do tty assigning for remote
commands... only for remote logins if I remember correctly...
my own take is to find an ENV variable that rsh transfers to the other
side and then feck with the /etc/csh.login /etc/profile to check is the
ENV set and if it is execute the script.. you might be using an
environment variable that isn't supposed to do this like DISPLAY or someat
but a bit of overloading doesn't affect much :-)
