I voted for Danubia, of course. It's once again like a very big Belgium, nationalities first, territories second and supreme courts having to constantly deal with authorities to be hurt or not. I also remember another winning entry from another MotF called "The Federation Of Leithania" which may not be as detailed (as it's supposed to succeed instead of crumble), but imagining day-to-day news in both bourgeois and proletarian version of federal Danubia/Leithania would be quite awesome.
