got some answers back: 1) the Mono class libs do fall under MIT X11 (runtime and C# compiler are GPL or LGPL). even though i dont consider a single class 'substantial', the copyright does need to be included in a single class that use in my own project. this isnt a problem because the copyright is very open. 2) not all Mono authors transferred their copyright. this makes me think that you could contact those authors directly for the code, and ignore the Mono license if they let you use it. aside, a quick search through the code shows that most of the source files are marked differently. even if you find the same class twice, 1 instance will include the MIT X11 license, while the 2nd version will not. i did come across a Novell copyright in some of the files too.
