Getting back on topic though, I mentioned on here last year that I had
installed debian and Mythtv on a Pogoplug to run as my Master backend.

I was advised by several people on here that it was not a good idea due to
the processing required by the rescheduler processes, and that they would
take a lot longer.

I changed tack, and my Myth Master is still the power hungry dual-core AMD,
but it now shuts down when not required, and the Pogoplug acts as a
"wake-on-lan concierge". When Myth shuts down it writes the wakeup time to
the pogoplug, which then executes WakeonLan at the desired time.

This was all due to the motherboard  not doing wakeup correctly on it's
own.Works well for me, and it has reduced my bills significantly.
