Thank you for your contribution, Nuvoloblu. 
I particularly like the idea of military transit in your first post on the previous page. I think various types of open borders agreements are necessary in order to prevent what would seem to be ridiculous situations of a military wandering halfway across the world through neutral territory to wage war; sometimes within the neutral territory itself.
However, your final idea of that post, if I understand it correctly, seems to be placing too much importance on tactics, with the placement of units having effects on the abilities of other units within a particular zone. Just remember that Civ is a strategy game, not a tactics game, and any implementation of tactics distorts that focus.
