Suppose I have several PCs (call them Raspberry Pis, because they probably will be) each collecting data from local sources (eg temperature data via a local sensor), logging it to a local database, and making it visible via a local display on HDMI and/or via a web browser.
If I want to take advantage of the fact that they're all networked and allow each of them to pull the stored data from all their neighbours, what would be the simplest way to achieve this?
Database replication etc feels like overkill.
I don't really want there to be a "master", I'd like to think of them all as equivalent peers.
