I don't know anything about db4o (and I haven't looked it up) so I can't really say. I have no problem with you working on adding support for it, however, just as a forewarning, things might end up changed significantly as the project moves forward. That's not to say your work will be scrapped, just that it might not fit into the model of where things are heading. I suppose you run that risk with most any project though. On the other hand, transactional single-file storage _does_ sound like what I've been looking for. Something that's still in conceptualization is providing a fail-over network of Managers so that when the "leader" Manager goes down, a secondary Manager can take over. (This is something we're working on at UMR.) Being able to persist the Manager's state to a single file and replicate that among peer Manager nodes is pretty much what will need to happen.
