We shall see what happens in the future now that mySQL is GPL there's a chance we could package the whole thing up and GPL it. Will we do that? Maybe... maybe not... right now we're working on developing a sufficiently stable code base and adding new features and functionality that would make Zope self-destruct out of a feeling of inadequacy (if we're luckily Python will get caught in the shrapnel). We also need to figure out how to pay our bills too something people forget about sometimes.
