Hmm. Is this not a security flaw? How would this be implemented?

Using stuff like avahi you would still have to do some sort of RMI or
RPC protocol.

Instead of thinking of the system as a 'high power user that we can tell
to reduce power' we are aiming for a model that is a 'low power user
that only becomes high when the user is actually working'. I.e. what I'm
trying to say is that you can only save at most a couple of watts if you
dim the screen as everything else should be throttled down, even when on
AC, and then most users would turn the screen back up anyway.

complain and turn it right back up. :-)
