Yes, but is it not possible to "cull" sectors of the world which aren't in use by the client/player? That way you don't exceed the limit and also gain in performance? I think we'd need to do it like that anyway, out of performance concerns alone. For instance, it's irrelevant for Libya to exist on my PC while I'm in western Egypt (and vice-versa). I don't need it until I'm about to cross over into it. In which case, we could scrap the place I just left?
