The access token should be tied to a person/user, not a PeerIdentity, to allow the user to access the group from different devices/peers (simultaneosly?).

The authorization can be issued to one key directly or allow chaining.

First case is simple to implement, but requires several devices to share the same private key (for instace, PBKDF fro ma secret password).


Second case:
- origin signs the "master key": the key identifying the person.
- person uses its "master key" to sign various device/peer keys. This can be made ephemeral.

Again, that's part of PSYC. Psyc stores the list of active group members in the state, and multicast can query psyc about who is allowed to join.
