thanks for responding to this question also via: http://p2pfoundation.net/Special:RecentChanges?title=Talk:Complete_Guide_To_... Johannes asks: Regarding "*There’s a critical distinction here and that is that your code is out there and anyone can start a company to commercialize this code. Bear in mind that it is very hard (often impossible) to reverse a decision to open-source*": It is IMO an option to provide an open kernel, especially to ensure interoperability, so others can enrich by own components and keep code of other components private. Though I would prefer the donation model (instead of selling), because it offers the opportunity, that more people may use the software. In consequence the percentage of people willing to give can be lower to achieve a comparable earning. My question is: *are there examples of open code harvested by commercial developers*?
