+<p>Springless refers to moving away from the dependency on the Spring JMS API. A new JMS client API is being developed from the ground up to power SJMS.</p>
+
+<h4><a shape="rect" name="SJMS-Clustering"></a>Clustering</h4>
+
+<p>When using InOut with SJMS in a clustered environment you must either use TemporaryQueue destinations or use a unique named reply to destination per InOut producer endpoint. Message correlation is handled by the endpoint, not with message selectors at the broker. The InOut Producer Endpoint uses Java Concurrency Exchangers cached by the Message JMSCorrelationID. This provides a nice performance increase while reducing the overhead on the broker since all the messages are consumed from the destination in the order they are produced by the interested consumer.</p>
+
+<p>Currently the only correlation strategy is to use the JMSCorrelationId. The InOut Consumer uses this strategy as well ensuring that all responses messages to the included JMSReplyTo destination also have the JMSCorrelationId copied from the request as well.</p>
