I'd be interested in hearing how they handle the routing within the data centers. Is it all just ethernet, and whoever uses ND (IPv6's ARP) to announce an address gets data to that address routed, or is are there some kind of subnets in between? How do they avoid someone stealing an address in your pool?

4096 addresses is much nicer than just one, so I'm thrilled to see this change. Switching over from a tunnel right now.
