Suggestion for the Skydrive.
For me The price can be reduced If the two bases are nearby. (Like from the australian base to the usa base or other cases)
For example we are in the Australian base, to do the skydrive from the australian base to the American takes 10k dollars, but since the bases are nearby the price may be of 8k (For example).
Same thing if we are in the base of Eurasia and we want to go in the German base for the skydrive it takes dollars 10k but the two bases are nearby, and so the price can be reduced. For me it can be a good suggestion.
