|On AT&T UNIX, you can allow group write permissions to the /dev/tty.

	On most BSD-derivative systems no user other than the owner has
access to your tty, nor can you modify your own.  Talk requests and such
are done through a system of daemon processes which control user access
to each other.  This was done in order to remove the ever frustrating
moment when someone does a "cat</etc/hosts>/dev/ttyxx&" to your terminal.
