Project Zero isn't open source.<p><i>"This community is an experiment in a new way to build commercial software, an approach we are calling Community-Driven Commercial Development.<p>Community-Driven means that we want feedback, insight, suggestions, criticism, and dialogs with you, the users of Project Zero. This interaction will yield a better solution that targets the problems you have and a technology that truly delivers on its objectives.<p>Commercial means that this is not an open source project. We are still building commercial software here, as the licensing makes clear, but we are doing it in a more transparent fashion."</i><p><a href="http://www.projectzero.org/about/" rel="nofollow">http://www.projectzero.org/about/</a>
