I don't know all the details, but I don't think that's how it works.

At the moment, Meteor and Derby at least have the advantage of existing. I think that's the point Ramos was making -- Meteor is doing some cool stuff now, not that such things couldn't in theory be implemented in another language/platform. Actually, in the Python world, there is (was?) the Planet<http://www.planetframework.com/>framework, though it is proprietary and was quite expensive (looks like it's no longer active or available).
