What alternative would you suggest? I really like Keybase and can't seem to find anything that covers the same functionality - been keeping an eye out since Zoom bought them.
You configure a secret token and all servers which know the token automatically sync via BitTorrent. You don't need to manage lists of server IDs like with syncthing, it's completely peer-to-peer.
I'll miss coin flipping [0] dearly, though.

Are there any others to consider? It's been quite sad to see Keybase so stifled after being acquired. :-(
