+Invite: unicast message with group identification
+
+Group metadata: download from the swarm
+
+Message multicast ideas:
+
+1) Bittorrent
+
+Swarm downloads: when to update? Polling.
+
+2) Bitcoin
+
+How are transfers propagated?
+
+3) Fossil
+
+Create a new ID when a new message is created, propagate that, and use
+swarm to download the content. When messages history diverge, use
+merging. Try to solve a problem regarding message ordering.
