Dirk Riehle on the commercial Open Source business model

Dirk Riehle, one of the organizers of WIKISYM ( http://www.wikisym.org/ ) and a researcher for SAP has a great paper on how companies create, distribute and make money out of Open-Source software. It describes XWiki's model fairly exactly, apart from the fact that since we chose to use only the LGPL license for our product we won't be pushing for a double-licensing model anytime soon.
