== Summary ==

 * We need a power management interface to allow a GUI application to interact with power management in a consistent form, even though each platform currently presents an entirely different powermanagement layer.

 * We also want the system to be able to notify apps when a power event occurs.
 
 * It would be nice to be able to tie into [[http://live.gnome.org/PowerManager|!PowerManager]] in the future.

 * Or use perhaps GNOME Power Manager http://gnome-power.sourceforge.net/ with its DBUS and gconf backends?

== Specification ==
 
 * This interface needs to be able to parse config from all preexisting power management apps - pbbuttonsd, acpid, etc

 * Must be able to blacklist events

 * Must enable gnome etc to synthesize events so that, eg, flexiserver can suspend the machine.

 * Preferably present a dbus API for querying capabilities, calling events, and sending events

 * Packages must be able to register requirements to the power management system

 * APM policy must move to userspace

 * Proxy existing daemons so that their output goes to the PMI; pbbuttonsd has code to do this for PMU and APM, should be trivial to add ACPI.

=== Short term ===

 * Use flexiserver to call events directly in the short term?
 
 * Need to establish a list of PowerManagementSystemEvents for all power management styles to expose to PMI.
