EDIT: Somewhat related - regarding OpenGL, ReactOS' decision was to bundle only the version 1.4, because installing the graphic card's drivers will give you exactly the last version of OpenGL your card can handle, that is - if you'd be interested in accessing the card's capacity (beyond what the default bundled ReactOS driver will give you) in the first place. Many folks might not even be interested in such a thing, considering that not every one plays hardcore games, so why bother? Why bloating the entire system with something that can be left as optional?
I know this is a loaded question but I mean it seriously. The importance of legal aspects is highly varying, from matter-deciding to completely irrelevant. Especially if you have a government of a souvereign country like russia behind you, legal problems about redistribution or usage shouldn't be a big problem.
