Joining the network procedure

[Chat-Wane]

For now, the joining procedure is initiated by the peer outside the network. The other way around works too, but does not preserve the desired properties of the network.
Consequently, a peer inside the network should be able to invite someone else to join. It implies that the underlying indirection mechanism works too. It also implies that the answer provided by the peer outside the network correctly travels to the chosen peer inside the network.
