	Interesting.

	This is most likely because we don't implement the get_interface method
on the Object; sadly we don't (yet) implement this in ORBit2 - although
in that case we have all the hooks ready to do such a thing properly.

	It's going to be hard in ORBit I think; You prolly need to switch to a
method that uses 'is_a' instead of get_interface_method - how to do that
I know not; ie. it is quite possible to do CORBA_Object_is_a (obj,
"IDL:Foo/Baa:1.0");

	Sure - I hope the is_a method is exposed by your binding somehow. 

	HTH,
