Hi Ben,
is it possible to install Tsung and the load test configuration files on one of the servers? Gato did describe the Tsung setup or at least parts of it on wiki.igniterealtime.com (this host is no longer available). According to http://www.igniterealtime.org/community/message/204269 the current build has some memory problems it would be nice to test the current server before releasing it.
LG
