> Circuit breakers have pretty dramatic attenuation. You go through at least two to get from your power sockets to your neighbor's. Yes, but not enough attenuation to block powerline communications.

There's even explicit provision in the spec for neighboring networks, so that they share the bandwidth instead of stomping all over each other.
