So, we already have StatusNotifierModel, which at the moment is a DataEngineConsumer, but what you can do, is to keep that class, and instead of consuming a dataengine, it can consume a singleton qobject that will keep all the dbus operation and caching there. that thing would have signals of item added/removed/datachanged so it becomes easy to directly map this to a model. -- Marco Martin
