I wasnt sure if it was wildfire, but one of either wildfire or ejabberd had a problem with sending messages out of order, the seriality of messages can be patched into the inkboard, however its a standard defined into xmpp so I wasnt keen on patching for non compliant servers until the Inkboard was fully functional and stable.
Ill give it a test today, I certainly think having a test server is a good idea forward, just want to install the best candidate. Following work on Inkboard during the summer a patch was committed to ejabberd to fix the roster order bug which also affected us, so that isnt an issue in the newer releases of ejabberd
