Yesterday I found on YouTube the keynote I gave at the Open World Forum in Paris last September. I talk about what I consider THE business model for open source projects: a separation of a free community edition for deployment (for people that have time but no money) and a commercial edition in the cloud (for people that have money but no time). Obviously, the example I am using is Funambol... but I think it can be a model working for a lot more projects.
Caution: it is 15 minutes long. Too bad the slides are not visible, this was my best zen presentation sequence ever ;-)
