I would like to contribute to something in MQ as well.
I am going through the design documentation.
Would you like to assign an specific task to me or would you prefer me to start investigating the EJB3 Interceptor design?
Also, could you point to any other documentation on JBoss MQ. The one I have been looking at is http://www.jboss.org/wiki/Wiki.jsp?page=JBossMessaging
I will generate JIRA task soon. Until then, the unified interceptors and the remoting documentation is a good start, since this is what we're going to use to implement the JMS facade.
