I think this is possible, And will not take as much space as you would think. I am thinking an entire nation may weigh in at around 20 - 30 gigs(!) And if you have a VERY powerfull top of the line computer it will handle it, because it is not processing all of that data at one time. The only real problem i can forsee would be who is going to be willing to pay for the hosting of such a GINORMOUS region? I think we should really work towards this, we will not know if it is feasable or possible until we try. BEST regards, Psilaxs
