open source and classified software

[Lucas Vogel]

Does anyone know of any articles related to open source software and
classified software? Can Open Source be used to develop classified software,
or is that an oxymoron? I'm trying to find anything that comments on the
possibilities(or impossibilities) of the two working together. 

Thanks
