FOSS Primer

While this article ( http://www.softwarefreedom.org/resources/2008/foss-primer.html ) was apparently posted on February 14th, it just came to my attention today. It is an in depth look at the legal issues surrounding free and open source software. While it seems to be more US oriented, it does cover copyrights, licenses, patents, and trademarks so if you are involved in any open source project you should probably read it.
