  Only 46!?!  ;-)

  At one site I'm working on, the conserver.cf file is nearly 2500
line, for a 3-server, distributed mode installation, controlling
more than 2000 console ports, across 25 terminal servers, and one
conserver host has close to 70 child processes under the main process.

  (Just remember the math in your configuration file (cons.h) before
you do the build...we're using maxgrp=96, but just make sure that
you can spawn enough processes to cover all of the ports that you
want to connect to, and make sure your host has enough RAM for
all of the processes.)
