Static interfaces are ones for which the IDL is established at
compile time; DII represents where the interfaces are established
at runtime.

The C CORBA binding for DII is pretty painful; the C++ binding for DII
represents where a Whopping Lot of the interface complexity comes in on
that side.

If CORBA is actually being used, it should be very easy to answer this
question.

Is it generating IDL and compiling it at compile time?  Or does it use
DII?

(This should be trivial to answer based on whether or not you use
#include <orb/dii.h>)

And when it is necessary to interface to things outside, how would
one do that?

If there is "no IDL," then this sounds like it is distinctly NOT a
CORBA-based system, as IDL is the basis for defining CORBA applications.
