Alliances?

[bcaiko]

The diplomacy threads in Gods & Kings got me thinking to the times where you friend CivA, which is friends with CivB, and CivB suggests this could be the beginnings of a makeshift alliance.

Why does it have to be makeshift? It would be neat if a certain tech or tech level allowed the creation of Alliances a la the Allies of the Great Wars.

I would like to see this but there would need to be a X amount of turns that all civics could agree/disagree to renew said treaty. But also add some micromanagement features into such deals like X amount of iron, copper, or other strategic resources be shared in such an event. Always Open Borders etc.
