I did not read your first entry back in 2018, as I’m not around so much as last years. Also over the years there have been many suggestions that have never been worked on. In my opinion this PR only serves a very specific use case (yours?) and I don’t want you to spend your time and effort (thanks for that) working on something that will hardly be used once implemented. Your words like “cluster members” reminded me of a file sharing software Direct Connect from many years ago where users could setup P2P hubs. Is this what you are trying to achieve?
