There are a number of ways to allow users to send messages to each other
WITHOUT requiring that everyone have write access to /dev/tty*.  One
that comes to my mind is to make write(1) and friends be setgid to
"write" and "chgrp write /dev/tty*".  This also permits us to prevent
the security hole that "write" currently provides with programmable
terminals, since write(1) could be taught to censor escape sequences.
