The module is now stable enough to be tested and used by the community. However, it currently requires the last *dev* version of Tripal 2 (released after November 1st, not tested on Tripal 3) and hopefully, it should be
compatible with next Tripal 2.1 release. I updated the README.md file to reflect the last changes and to describe how to setup the thing according to your use-cases.
If you can review the module there (https://groups.drupal.org/node/427683) and help in the “promotion” process, the module will be sooner (or later) released as an official extension.
I appreciate your time,
