I don't think that a CORBA-ObjC mapping wouldn't be too hard. CORBA has the 
issue of the formal specification in IDL, though, which is OK if you need 
formal specification anyway (C++) but isn't if you don't or already have 
it some other way (ObjC, Protocols). So there would have to be an 
IDL<->ObjC header file converter.

The other, bigger can of worms is the ORB's run loop and event model, which 
is rather incompatible to OpenStep's and not specified down to the last 
iota: Some Orbs spawn a new thread for each incoming request, some don't, 
some have that configurable, some don't. With a multithreaded Orb, the 
entire of GNUstep must be thread-safe, etc.

OK, on thinking about it again, I revise my opinion. I think it is doable, 
but it's very hard.
