We are digressing into technical details while there is no clear question.
The CORBA thread started with:

I am not sure that you are right.  But why would you want
an NSCORBAConnection in the first place?  I think it could
be usefull for the following reasons:

- Interoperability between GNUstep and non GNUstep applications.
- Keeping the clutterfree semantics of the GNUstep DO system.

But this means that you want more than just GNUstep DO 
implemented on top of CORBA. 
And than you need to make some decissions:

- Using an interface repository or using IDL
- Using an implementation repository?
- How to assign IDL types to objects etc.

And although I really would like to have a clean CORBA
implementation added to GNUstep this will require
some substential effort.   
So if you want to embark on some technical discussion,
I would like that.  However I am not going to spend
significant time on this by myself.  
If you want to spend time on this I will join, if
not, it will stay a nice hypothetical discussion.

The other point you raised in that e-mail:

I do not think Fresco is a good thing for GNUstep.  But for me,
it is purely a personal interest to see how it will work
and play a little with it.
