Hyperkitty is the demo that a few people have been working on, including Toshio at the sprints, but there are others in play (eg, recent posts to this list). Also, Hyperkitty is currently based on somewhat limited technology (the notmuch indexer). I'm not sure it would be up to the demands of data-mining. Of course, if Toshio says it is, listen to him, not me. :-)

For the record, the current version of HyperKitty has moved from a notmuch backend to a mongo database allowing a much more flexible data storage scheme. This is the one you can see online at: http://mm3test.fedoraproject.org/ The demo is getting more and more complete with month view, recent activities, thread view, basic search functions and categories. My only problem is that we seem to have some memory leaks at the moment :-/
