[RFC] propose to develop a rfkill daemon

[Joey Lee]

Dear all experts, 

I am working on implement function key features in gnome-settings-daemon
to control wlan/bluetooth/wan. There have some use case need control
rfkill by userland applications, some netbook use one function key to
control 2 - 3 wifi devices. On windows, it's also implemented by
userland application.

Before HAL removed, I enhanced gnome-settings-daemon to control rfkill
by call HAL dbus function. But, there have no middleware/daemon can help
applications to control rfkill state after HAL removed.

Kay kindly give me some idea, and after google this topic, found the
following RedHat bug for gnome-bluetooth:
 https://bugzilla.redhat.com/show_bug.cgi?id=514798
and
 http://www.spinics.net/lists/hotplug/msg02464.html
 
At last, RedHat direct add user acls for /dev/rfkill by udev rule.
But, looks like a rfkill daemon still need for
gnome-bluetooth(bluetoothd).

Follow Marcel's comment: the _better_ way is implement a "
D-Bus enabled RFKILL daemon that integrates with PolicyKit"

I want to develop a rfkill daemon like upower and udisk, to provide
D-Bus methods and integrates with PolicyKit, maybe the name is urfkill.

Does it a good idea? Appreciate any suggestions for this topic.


Thank's a lot!
