Well, since I am not sure what would be the best way to do it - could
you please give me a hint how to call something depending on
properties? All I see now from hald documentation is /etc/hal/device.d
subdirectory - where I could put the script analizing HAL_* variables
and starting/stopping my daemon.

Actually, current HAL has nothing about batteries. So I just hacked my
own lwm.fdi with some properties which make sense to me... The "unit"
properties is void for logitech (well, I am not sure, but for a
moment...) - but in can be "mWatt" etc.

Yeah, putting these properties into specs could be useful...
