I'm not convinced Gtk+ is the place to be experimenting with D-Bus
integration. Can't we do the experimentation in a libgdesktopbus or
libgnomebus or something, with convenience API for single-instance,
notifications, etc., that hides libdbus, and if it turns out that in fact
everyone wants it, push it into Gtk+ later?

In fact, there is already libnotify, which is a C wrapper around libdbus
(hiding libdbus completely, IIRC) to do notifications.
