Stuff that needs doing ...

 - Some kind of rudimentary IP based allows for upsd

 - Actually use the password field for crude security

   - upsmon will actually transmit the password right now, but upsd doesn't
     check to see if it is valid or not.  I'm planning on using the password 
     field for the next item, which lets clients "log in" ...

 - Have upsd command the UPS to "off" when all clients have checked out,
   or after some timeout, whichever comes first...

   - Local machine shutdown in upsd
   - Send "shutdown with grace time", then shutdown *fast*
