I have a feeling providers will start managing/reducing the excess capacity headroom in their networks. And will start looking at ways to wring more money out of their current customers. Some rocket science accountant somewhere should be working on a way to maximize the chargable usage by just shifting the window bins back and forth until he finds the maximum.
This would work well for end-users. Buy outbound time on inbound-heavy networks, and vice-versa. Route updates are too slow to move the content around, otherwise a really savvy and cheap buyer could keep thier "current" server in the dark part of the planet full time and get excess bandwidth for next to nothing all day. -- Eric A.
