        My feeling is that you are trying to duplicate the orbit-small
functionality, and yet I can't understand quite why you want to.

        Well - at some stage, someone has to do the conversion - either to
a C like structure ( as for ORBit-small ) - but this is hardly _that_
tough, or to a CORBA_any and use DII / DSI ( using the standard DynamicAny
interface ).

        I really don't see what you're adding either in terms of
performance or complexity reduction.

        Can you explain some more ?

        Regards,

                Michael.
