Base on many conversations with development folks, I find speaking to the distributed systems annex is much more natural then speaking about CORBA. CORBA is big and it is not Ada so I have to do alot of explaining to even begin to have a meaningful conversation. I don't have this problem when discussing the distributed systems annex which nicely maps distributed semantics to the language. I half expect a compiler vendor to implement the distributed system annex with CORBA. Given such a beast, I get the best of both worlds and the distributed systems annex provides a "natural" intermediary step to getting folks to take deeper steps into CORBA. From my limited knowledge of the specifics of CORBA, I don't think this would be a major effort. If this is true, then any vendor should be able to support Ada's distributed systems without a huge investment since CORBA solves many of the nitty-gritty implementation problems. -- Samuel T.
