Just out of curiosity, does your powersave daemon meet the requirements
that I jolted down here?

No one should reinvent the wheel but I think the policy enforcing bits
needs to know a lot about / interact with the desktop bits that happen
to be running. So, having a daemon that enforces policy running at the
system level is wrong I think. What we want to provide with hal is the
mechanism (e.g. methods Suspend, setLowPowerMode) that allow things like
gnome-power- manager to easily and securely enforce policy.

dbus-send is your friend here.
