Thanks to you all, and the NetBSD team, I have a NAT gateway machine
tucked away and humming along with no monitor or keyboard attached.
It's a dream of about a year come true.

I'll be leaving the power on most of the time, but when I do shut it
down, I'd sort of like it to:
   1) Not shutdown if one of the subnet machines is sending packets
      through the gateway.  It would be nice if it would inform me
      what machine it is waiting for.
   2) Make sure I am logged off before it shuts down; not just a
      simple delay mechanism.

Where does one look for scripts to do these kinds of things?  TIA
