  We could have that, yes, on top of the general 'message' signal
interface:

void specific_message_handler (BonoboApplication, const CORBA_char *str,
CORBA_int i, gpointer user_data)
{
/* ... do something ...*/
}
bonobo_application_add_message_handler(app, "specific-message"
bonobo_message_ANY__STRING_INT, listWindows_handler, data);

  The closure could look at the received GValueArray and compare the
types with the ones that it is designed to handle, before invoking the
callback, so that we can indeed have type safety.  [ Could it be
possible to make a macro that creates a closure for a list of argument
types?... ]

  Ok.  I'll have to look more closely at what gnome-terminal does to
better determine the requirements for such a thing.

   Sure, with bonobo_application_add_message_handler we can add our own
hooks.  Are you thinking what I'm thinking?  To get 'listWindows'
automatically implemented by libbonoboui?  That would be very
interesting! :-)
