IIUC we use such a mechanism in a few Telemetry projects to share
information between agents.

For example, Gnocchi metricd workers talk together and provide each
others their numbers of CPU so they can distribute fairly the number of
jobs they should take care for. They use that same mechanism to know
if/how every agent is alive.

We've been using that technology for 3 years now, and we named it
"tooz". You may have heard of it. ;-)
