GGI3D and CORBA (was Re: libggi3d)

But is there any IDL compiler that is not associated with an ORB? My
understanding was that if I compile my IDL with something like ORBIX or
ORBit, the implementation parts of the IDL compilation will use the ORB.
Since preferably I'd be using the interfaces defined and not the implementations
how could I avoid going through the ORB service?

This is the part I don't know about. Could you elaborate...how does CORBA
know if I'm in the same address space, if I'm using the interface objects
and not the implementation ones...or do I have to use the implementation
objects directly?
