In one of the older BSD (as in from UC Berkeley) releases (I think
it was 4.2) there was an ioctl that would let you spy on a tty.  I
don't remember the ioctl params or name of the ioctl parm but it
was there.

If it's not in the current source (FreeBSD source) you hopefully
should be able to find the BSD sources somewhere on the net.
