So far, we have [inter-node encryption](https://github.com/rustyrussell/lightning-rfc/blob/master/bolts/01-encryption.md) and [transaction negotiation](https://github.com/rustyrussell/lightning-rfc/blob/master/bolts/02-wire-protocol.md).
Routing between non-adjacent nodes is currently done manually using the 'dev-addroute' command; later on daemons will
advertise their IP addresses, and publish routes and fees. These details are currently being
hashed out on the [mailing list](https://lists.linuxfoundation.org/mailman/listinfo/lightning-dev) and the IRC channel [#lightning-dev](https://botbot.me/freenode/lightning-dev/) on Freenode.
