Well, the version with just the Netherlands is now public.

At least you now have about 2/5 of the map, and a complicated harbour and airport system to play with. I may have to start the Benelux map from scratch to get it to fit in the size limits, especially if I let it have a minimap like on the Netherlands version. But RvW is currently looking in some methods to make the file smaller, so there's still hope!
