Zend_Queue_Stomp provides a basic client to
        communicate with Stomp
        compatible servers. Some servers, such as Apache ActiveMQ and RabbitMQ, will
        allow you to communicate by other methods, such as HTTP,
        and XMPP.
    
The Stomp protocol provides StompConnect which supports any Java Message Service (JMS) provider. Stomp is supported by Apache ActiveMQ, RabbitMQ, stompserver, and Gozirra.
