This is somewhat of a hack, but the IWDDBusAbstract is a very convenient abstraction to DBus objects. The only piece that restricts it to IWD is the hardcoded IWD_SERVICE. Instead we can pass in a keyword argument which defaults to IWD_SERVICE. That way other modules (like EAD) can utilize this abstraction with their own service simply by changing that service argument.
