"I'm not aware of any message broker that lets you throttle messages on a per-consumer basis" depending quite what you mean here, ActiveMQ supports this. "With an MQ, no component of the system has a global overview of load." except the MQ surely? Again, ActiveMQ supports multiple consumers on one queue and handles balancing the messages to workers at the rate they require.
