Yes, this is exactly the direction I was hoping we could move to.  We
would like to have some sugar to integrate this into the GNOME
environment.

You really do not need to do this, as you would be able to query
objects and load interface definitions from either the IR or the IDL
file.

So the top level object you pass to "initialize" (your Host) would
basically implement your toplevel object, and from there you could
walk the tree of objects.  Something like:

	workbook = host.query_interface ("IDL:Gnumeric/Workbook:1.0");
	sheet = workbook.get_sheet (0);

Please, do so.  They must become part of Bonobo/idl.

Looking at what Microsoft has in this area could teach us a few tricks
as well.
