[Rooftops] NxtGen mesh to support an end run around ILECs?

[Jim Youll]

I've been traveling (and carrying this heavy thread around in my laptop cross-country and back a few times).
Now that i'm wanted to point you guys to work that suggests that your concerns can be overcome... in real networks, that operate right now
