I think that is where we are headed, but it isn't where we are right now (at least at the
committership level).  The Board will likely be seeing a proposal for Mahout as a TLP next
month (we are in the middle of a release cycle so we don't want any distractions at the moment).

I think Tika can stand on it's own, too, and the community there should have the discussion.
  At the same time, I don't want to "kick them out", either, but I would encourage them to
at least have the discussion.

The Ports of Lucene are a bit tricky in my mind.  Both of them are auto-generated for the
most part, so they don't require a super amount of work to produce, but they don't really
seem to be standalone either other than there isn't much committer overlap.  I personally
think the status quo works really well there, but again, just my opinion.

That leaves Solr and Nutch.  The past vote has answered the question for Solr.  I guess I'd
encourage the Nutch community to have a discussion on it.  There isn't much committer overlap
there with Lucene or Solr but there is some code overlap.  Personally, I think the crawling/plugin
stuff could spin out but the core Lucene/analyzers stuff merits a review and a merge.  Again,
that is up to Nutch to decide.  Last I looked at Nutch they were moving to a more modular
architecture that focused on crawling and handed off the other stuff to things like Solr and
