No joke – implementing and running such things requires a truly enormous amount of time and effort (during the existence of Actea, I did much more than during all the Expeditions; I, of course, take into account my own journals and descriptions of the country that no one reads, but nevertheless).
Another option is to make a lighter version of all this; decide on the technologies and other things, simply add them to the description of your country, and use them for role-playing. This can be done, but it doesn't seem like a good idea to me; remember, for example, Arza's posts today about how "I've already studied this on NS!".
