My device better be internal now! If somehow my 192.168.0.x net is 
available to the world, I need to know about it!

device at ckent.org is an arbitrary email address I gave the gadget to let 
me know where an email is coming from. there's no DNS resolution for 
device.ckent.org.

As long as the gadget can contact an arbitrary email server to send and 
receive, ultimately, I'm doing OK. If this requires more than the really 
simple code I am playing with, I have no problem adding a package to 
handle that - I just want to get the smallest package possible.
