I have a package I got from UCI eons ago that does most of what's
been asked for.  It's called "ttyd" and is available by anonymous ftp
from oddjob.uchicago.edu as pub/ttyd.tar.Z.  I suggest the those
interested look around in UCI's anonymous ftp area (wherever that is)
first because they may have a newer version.  In the copy I have,
the wall command tends to glitch a lot due to a design error.

With ttyd users should set "mesg n" and then run a suid program to
declare the action they want taken upon connection requests.  The
action can be to pass messages on to the tty, to refuse messages, to
mail them to a given address, send them to a file, pipe them to a
program, or connect them to a specified socket.  There is no
filtering based on the originator, although a wall or write from root
will still go through.
