This is a more-or-less unrelated technical question, but:

As I understand it, CORBA provides an abstraction layer whereby I can call
a method on an object without knowing whether my call is a real function
call (i.e. to another object in the same process space), some kind of RPC
mechanism (i.e. to another process on the same computer) or a networked
call.

The the target and caller can end up linked in the same process, or they
might not.  From the point of view of CORBA, this becomes a detail of the
compilation method chosen, and doesn't affect the how the program
functions (apart from speed issues).
