[rabbitmq-discuss] Is RabbitMQ indeed "hype ware"?

For what it's worth I've been using RabbitMQ in a production system  
running 24/7 for more than 2 year, running flawlessly. I wouldn't  
hesitate to use it again.

Whether it will solve your specific issues or not, I can't tell.

Also, I believe in the AMQP standard effort as I feel less "locked in"  
than with other solutions.
