With the ship date of my Raspberry Pi (details here) being brought in again, I have decided that the first raspi will be an Insteon "appliance". It will be a dedicated machine to run 'plcd' and be plugged into the PLM.

As it is dedicated to plcd, there is no possibility of it being restarted unexpectedly. Using the socket opened by NetworkThread, clients can be run on any machine, but more than likely as this is the appliance in charge of home automation, the appliance will run pretty much everything.
