Currently, the object invocation is via name services tied
to an X session, but according to a recent message on one of
the Gnome mailing lists, the plan is to move to a more
flexible scheme.  Eventually - I hope - this will allow the
use of the basic Gnome CORBA infrastructure (ie, basically
the Gnorba library) without the rest - which is definitely
useful on say a headless server implementing Gnorba
services.

I'll definitely keep an eye on not introducing additional
dependencies in the Haskell layer - like in the GTK+Haskell
binding, you can import and use the `Gdk' module without the
`Gtk' module.
