Relay per groups or per network?
I have several questions regarding relay peers:
1) Are relay peers required to be in the same group as the peers that use them, like it happens for RDV peers?
1.1) Can relay peers outside the group a peer is communicating in be used? (like from the initial seedingUri of the network bootstrap).
2) How do relay peers get discovered besides multicasting?
2.1) Is there a mechanism similar to the rdvService that announces new relay peers as they join the network(group?)?
2.2) Does each relay need to subscribe to the central seedingUri used for bootstraping the network and the peers will use them when their destination is not directly accessible? (this would be the less preferred).
I`d appreciate your help.
