Right, although I think I currently just call them

 /org/freedesktop/Hal/devices/acpi_BAT0 etc.

The acpi-addon should be launched for every device object
but should check that no other copies of itself is running.
There are several ways to achieve this, e.g. taking a lock

There is indeed a Wiki, see

Maybe that's just me, though :-)
