It looks similar on the surface, but scope and goals are different: * BinaryRPC = direct request/response calls with optional QoS (per session). – No exchanges/queues, no routing keys. – One logical stream, messages mapped to handlers. * RabbitMQ / AMQP = full message-broker with persistent queues, fan-out, topic routing, etc. So you could say BinaryRPC covers the transport/QoS part of AMQP, but stays lightweight and broker-less. If an app later needs full queueing we can still bridge to AMQP, but the core idea here is “RPC first, minimal deps”.
