Hi @magp18 - thanks for your questions! Peer to peer sync is not currently on our roadmap.
I noted your link you cited, which was actually a write up I did about running a full fledged CHT instance in a fully offline scenario, not about peer to peer sync. That said, it was indeed later referenced as a possible work around for when CHWs were entirely offline, how they might use an offline CHT instance instead of using the non-existent peer to peer solution.
Could you describe what you hope peer to peer to solve for you? It would be great to understand the problem you’re facing so we can appreciate the challenges folks in the field are facing!
