For my undergraduate research project, I am doing a comparison of
CORBA and Ada's Distributed Systems Annex for distributed computing. 
I have been able to find plenty of information on CORBA from a C++ or
Java perspective, but little about CORBA with Ada.  Also, I do not
know where to look for good sources on using Ada's Distributed Systems
Annex.  Does anybody have any suggestions on good places to start
looking for this information?

Thanks,

Andy Berns
