The "Playground" instructions say:
If we run otherReplica.getLatestDocs, we'll get an empty array. It doesn't have any documents in it yet. Let's put this replica in another peer so we can change that!
In fact, my otherReplica did already have the documents. Is it so that as soon as a replica is instantiated with a shareAddress, it will directly sync if it is nearby?
