Between 1-2 is possible, we do this for EJB 3. In EJB 3 we use JBoss Remoting to send the invocation from the client to server, and make sure that the metadata is serialized with the invocation. For 2-3 although I have not checked properly, I believe that it should be possible to solve this by using the org.jboss.aop.metadata.ThreadMetaData class. Look for ThreadMetaData in http://anonsvn.jboss.org/repos/jbossas/projects/aop/trunk/aop/src/test/or... to see how it is set up and see how it is transparently obtained from the invocation in http://anonsvn.jboss.org/repos/jbossas/projects/aop/trunk/aop/src/test/or... ThreadMetaData can be found here: http://anonsvn.jboss.org/repos/jbossas/projects/aop/trunk/aop/src/main/or...
