How to do active-active cluster in 0.20

Hello
In this email thread,
http://qpid.2158936.n2.nabble.com/how-to-install-Cman-packages-in-fedora-18-Using-quot-qpidc-0-20-quot-td7588818.html
Alan Conway said cluster.so module has been discontinued and one should
use active-passive cluster. Is there anyway to do active-active
clustering in 0.20 release? If not, is active-active clustering going to
be supported in any the future releases? thanks
