We have 5-10 nodes that are already talking to each other via a RabbitMQ broker.
A few of these nodes may be publishing low bitrate multimedia content, and new
ones may join the network.

The idea is to re-use the RabbitMQ broker instead of using a separate video
server, where we can view all the logs (queue sizes, etc.) on the same webui.

Also Marton mentioned a use case here:
