Here's a message from the author on April 15th:

http://comments.gmane.org/gmane.comp.security.phc/1583

He lists these weaknesses:

   v0 Weaknesses..
   * fails basic randomness tests
   * key scheduling is ad-hoc
   * effect of m_cost parameter is coarse
   * lacks a rigorous security argument

   v1 will address all of these weaknesses

SFAIK, we have not seen version v1, and v0 is still not in an
acceptable state.  I don't think there's anything else to say about
Tortuga unless there is a v1 version.
