[feature request] common network-settings between different frontends

It would be nice to share network / connection settings between different network-manager frontends such as nm-applet, cli or kde based ones. Therefore it would make sense to move the place where the settings are stored out of the gconf-tree to a more common place like e.g. ~/.config/network-manager and store the settings in a common format e.g. XML-based. To encrypt the wep/wpa etc keys in the config file a symetric encryption algorithm like AES could be used and the required passphrase for that algorithm could be stored in the respective session store like gnome keyring or kwallet. The same mechanism could also be applied for systemwide connection settings.
