Spawning new proc and obtaining BonoboObject * in (*BonoboFactoryCallback)

Greetings and thank you for all the beautiful code,

I want to produce a BonoboObject (which is owned by its own process) 
within (*BonoboFactoryCallback) ().  I am having trouble finding a 
workable means of doing so.  I feel like I'm missing something simple 
and obvious, like a way to get the BonoboObject * from an object 
reference (I can find no such function, doesn't mean it doesn't exist). 
 I want to use g_spawn_async and have my process store an ior using 
gconf, then wait a second, then get the ior and 
CORBA_ORB_string_to_object() it, then somehow derive the BonoboObject 
pointer from the object reference.  This is brutal at best, I know.

Is it possible and/or legal to obtain a BonoboObject * from a 
Bonobo_Unknown?

Should I continue to pound on the fork() and g_main_loop way, which I've 
been unsuccessful at?

Should there be a convenience function for spawning a process from 
(*BonoboFactoryCallback) ()?  If so I will try to write one.

To further complicate things, the process I seek to spawn is multi-threaded.

Thanks in advance, apologies if I'm missing something obvious, but if I 
don't get past this soon I'm going to lose my mind.
