"A portable clean-room implementation of IBM's SOM. Includes DSOM capabilities with CORBA IDL and IIOP."
http://sourceforge.net/projects/somfree/I'm not sure for how long was this project on SourceForge. But it looks it had been some activity recently (2013-01)
I don't know much about it, but I hope it can also help us to have a open source clone of SOM on our platform. The compiled files are only available for some *nix flavours, but maybe it can help us on the future.
It is an open source project under the LGPL V3 license.
UPDATE: I noticed the project was registered 4 days ago. And the source code it says is from "Roger Brown's Toolkit"(LGPLv3)
