The standard Unix way (tm) is to use wall.

In Solaris, wall -a sends it to the console and ptys so you'd see it in
every xterm.  Linux doesn't have a -a option and I'd assume that's implied
by default.

I usually add my message to /etc/motd so and new logins get it and use wall
to hit all current logins.
