If you assume that datacenter bandwidth is cheap and the last mile is expensive, then this problem can be trivially solved by tunneling all of your traffic through an IP address hosted at a nearby datacenter. Unfortunately it's difficult to achieve this sort of innovation on a large scale, because we don't have enough IPv4 addresses, and everyone's dragging their feet on the IPv6 upgrade.
