On second thought: bonobo-idl.

[Miguel de Icaza <miguel helixcode com>]

I have been thinking a bit about the client side, and I believe it is
not as hard as I initially estimated to do the client side of the
stubs with a GObject-like structure (using BonoboObject as the base
class).

I will give it some more thinking and post my results.  For now, I am
heading back to hack the server side.
