+ * Two approaches - one presented below a DBusQtConnection
+ * object which is a Qt wrapper around DBusConnection
+class DBusQtConnection : public QObject {
+  Q_OBJECT
+public:
+  DBusQtConnection( QObject *parent=0, const char *address=0 );
+
+  bool         open( const char *address );

+  void error( const char* error );
+private:
+  DBusConnection  *mConnection;
+  QSocketNotifier *mReadNotifier;
+  QSocketNotifier *mWriteNotifier;
+};
+ *
+ * Second approach is to have a static Qt dispatcher like:
+class DBusQtNotifier : public QObject {
+  Q_OBJECT
+public:
+  static DBusQtNotifier* dbus_qt_notifier ();
+  void addConnection (DBusConnection* connection);
+signals:
+  void message (DBusConnection* connection, DBusMessage* message);
+
+private:
+  DBusQtNotifier (QObject *parent);
+private slots:
+  void processNotifiers( int socket );
+private:
+  //implemnted in terms of QSocketNotifiers
+  QAsciiDict<DBusConnection> mReadNotifiers;
+  QAsciiDict<DBusConnection> mWriteNotifiers;
+};
+ *
+ * First one gives us a full wrapper for DBusConnection (the Qt way),
+ * the other exposes DBusConnection, so would be easier to maintain
+ * and keep up while DBus evolves.
