To your points: - Nothing much I can say about stability and security, but then again, we're not saying it's stable and secure yet. Besides, people trust Oracle without seeing their sources, don't they? - If our startup folds, I doubt we'll drag our source to the grave. That said, maybe it gives our users incentive to make sure we don't fold? :P - There are closed-source MySQL storage engines out there with whom we'd rather be compared (TokuDB, Falcon (is Falcon open-source?)). We just don't want to close any doors yet. If it makes good business sense, we'd be glad to open the source.
