[xwiki-users] state of xwiki concerto

Hi, I am interested in trying out xwiki concerto but I am unable to download the installer jar from its website at http://concerto.xwiki.org/xwiki/bin/view/Main/DownloadAndInstall. Does anybody know what is the current state of the xwiki concerto project? I understand that xwiki concerto was a research project that ran until sometime in 2008 and I am interested in knowing what progress there's been on it since then (if any). i.e. does the main xwiki project now maybe include support for replication of xwiki content in a distributed environment? Any insight on this would be much appreciated! Regards, PM.
