I wanted to mention MQTT (mqtt.org) as good lightweight protocol that has many implementations.
I was surprised author made no mention of it (mqtt.org) but come to think of it it might be because author is specifically looking for queues it seems and MQTT works better as a PubSub, and its durability story which seems the main focus of the author is way different with very cool features - QoS - for delivery reliability but still not a classic queue
