Yes ? Is it obvious in a client code to handle an exception (print the
exception message) that has not been declared in a server spec ? Is it
obvious to ensure remote asynchronous transfert control in CORBA ? How
do you implement share data (matrix and slices) ? And atomic
operations on these data ?  These are of course examples but it is
very easy to find features that are impossible or complex to write
with CORBA (even remote object features) and that are very easy with
Annex E. Of course, you will be able to implement complex features
with CORBA, but you're going to write everything with some kind of
message passing (or asynchronous RPCs) when DSA would provide exactly
what you are looking for.

Of course, it could be very interesting to implement DSA on the top of
CORBA because in some respects, "<DSA> offers functionally everything
(and more) than <CORBA>" :-)
