I'll prepare an upgrade of the clustering code to the Carrot2 HEAD. There have been a few fixes, so it is worth it before the release.
If anyone objects, please speak up. Also, what's the preferred way of submitting that (remember it is a few megabytes) -- JIRA? Direct contact with somebody with commiter rights? John, you committed it last time, if you have any requests, let me know.
