Comment (by hughsient at gmail.com):

 Okay, So far today:

 * OHM suspends the system when you press the power button
 * OHM dims the screen on battery power
 * OHM dims further when momentarily idle
 * OHM sets a key that indicates we should turn off dcon (however we decide
 to do that) when the system has been idle for a long time
 * OHM allows a primitive inhibit key (needs a proper dbus api)
 * OHM allows you to tweak all the defaults as root and allows you to
 control what can be changed on the session
 * OHM reports the battery state to the session (percentage)

 TODO:

 * Report lid state correctly (99% there, just need to map udi's to values)
 * Do the xrandr callout or in compiled C.
 * Inhibit API for display and system. Need to discuss this on list first.
 * Port the accurate time remaining algorithm from g-p-m.

 I'll do the first two TODO items this evening.

 Richard,
