Which can be conveniently wrapped around an API that would take care of
this.  I do not believe this is technically impossible, but might
require some careful coding (and its good that now people know where
these pitfalls are).

I am not so sure.  OpenOffice can talk to CORBA just fine and Netscape
had the largest deployed corba ORB in the world (It was taken out of
Mozilla because it was a third party technology).   So it is not really
completely out of the question for these large projects.

You might have noticed that I carefully avoided the word Bonobo on my
original message. 

Anyways, if you want to go for short, you do not even need the C CORBA
binding.  You can use directly the engine which lies underneat Orbit
(Michael pointed this to us when we were looking at doing a
CORBA-for-Mono implementation: all the hard bits are accessible *without
the C binding in ORBit2).
