I followed this post http://qpid.2158936.n2.nabble.com/Dynamic-routing-between-disconnected-exchanges-td7598100.html and was able to get message relaying (qpid1 -> qpid2 -> qpid3) working by setting the federation-tag option in my /etc/qpid/qpidd.conf file I'll have to explore that option further and try to understand what it does. --Sam
