Comment CORBA will do most, if not all, of this. (Score 3) 132
CORBA will allow you to do most of what you want, you just have to use multiple ORBs.
I am part of a project that developed a CORBA facility, in conjunction with people from Norway. We each took the IDL and developed a client and server each, using different ORBs, platforms and languages (Delphi, C++, Java, DOS, Unix, NT), and managed to get them all talking to each other within 30 minutes of testing via the Internet.
In addition, there are products (albeit expensive) that bridge CORBA and COM, and I have had Visual Basic talking to my CORBA objects, and vice-versa.
As you said, there are plenty of open-source ORBs, each with their own set of benefits, but they should all be able to communicate via IIOP.
I'm fairly sure that omniOrb, ILU, MICO, Sun's JDK 1.2 and TAO/ACE will all co-exist happily, and are all gratis, and all apart from the JDK are open source.
Perhaps I am a bit biased, given that I've spent the last 5 years developing CORBA products...
