I've put up an etherpad page for the OpenHDI project and hackday here:

The current code that Guo and I hacked on (rewrite in javascript and
flask) is here:


I've also registered openhdi.org.

too. In addition to myself and Guo, I believe that Dirk Heine and
Friedrich Lindenberg will be participating. If you're
