I second that, especially since the DBusMenu stuff has been on my todo
list for quite some time (though not at a very high priority). Basically
what you would need is a proxy that exposes the menu using the
com.canonical.dbusmenu interface [0] and instead of having
gnustep-gui/back doing the drawing and event handling for the menu,
you'd register that proxy with the com.canonical.AppMenu.Registrar D-Bus
service [1]. The global menu will then issue callbacks that drive the
menu. (At least that's my superficial working theory of how it should work)

The problem is that DBusKit does not support exposing objects right now,
but since there is interest in this from somebody who is not me, I'm now
officially motivated/coerced to finally finish that part of DBusKit.
Most of the difficult parts are done, but I'm still lacking code that
takes care of registering exported objects with the D-Bus daemon.

Additionally, a working mapping from NSMenu to dbus-menu might be
valuable outside the GTK theme. I think it would be nice to be a bit
embracing and also do the integration the other way around, e.g. by
modifing the Étoilé menu server to handle the menus for applications
written for Ubuntu's global menu.

Cheers,

Niels
