He says, "Think about that; am I being naive or wouldn't just not
starting the service have the same effect without incurring the
overheads associated with the firewall?"

I don't know about that.  Mmmnnn, it's nice being able to use something
and not have others access it.  I was using webmin to play with
webalizer yesterday, and I like the fact that my firewall won't let
people outside my lan play passphrase games on it.  Overhead?  A firewall?
