The JavaPolis 2006 keynote by Marc Fleury covers the five models within the Open Source development community. Marc explains the potential path towards professional open source based on his experience with the JBoss Application Server. In his animated way he looks at what makes the model tick and who ticks it. In the last part he talks about the digital foundation being equal to (Virtualization + SOA + Web2.0) ^ OSS. A very interesting and entertaining keynote. You can view the video + sync'ed slides @ -Stephan
