Now here is an open source (or at least partially open source) project that may have a strong chance of drawing legal action from Microsoft: ReactOS. It is a free, community-driven operating system--currently only in alpha--based on the design of Windows XP/2003. According to developers: It aims to follow the Windows architecture designed by Microsoft from the hardware level right through to the application level. This is not a Linux based system, and shares none of the Unix architecture. There are some promising aspects to this effort, although there are also some foreboding, clearly similar precedents where Microsoft has called out its legal cavalry. Here's more.
