I'm quite sure this would be possible using the "tie" approach (where a
template technique is used to connect skeleton and implementation using a
pointer), as opposed to the standard BOA approach (in which the implementation
class inherits from the skeleton class).  omniORB supports the tie approach
through a command line option to omniidl2, if I remember correctly.  You would
then create two tie objects (one for each interface) that point to the same
implementation object.  It's almost as easy to use as the normal BOA approach.
