Had to change the network interface from DialPeer(peer.ID) to DialPeer(peer.PeerInfo), so that addresses of a provider are handed to the network. @maybebtc and I are discussing whether this should go all the way down to the network, or whether the network _should always work_ with just an ID (which means the network needs to be able to resolve ID -> Addresses, using the routing system. This latter point might mean that "routing" might need to break down into subcomponents. It's a bit sketchy that the Network would become smarter than just dial/listen and I/O, but maybe there's a distinction between net.Network, and something like a peernet.Network that has routing built in...)
