The whitepaper for this particular system is far from finished.  It's not ready for public viewing, and right now stands only as a technical document.  Don't expect to see a big announcement on when it will be released or implemented, as we have already started integrating it by implementing difficultyshield outside of core.  The best advice I can offer until this whitepaper is ready is to read the sources.  Keep reading them on every commit.  Watch how it changes.  I'm not going to hype something in a lame attempt to push prices up.  I offer code.  If you want to know what it is or how it works, it's there for you to read, and will only continue to grow and evolve.

TL;DR - I'm not going to simply tell it and hype it.  I'm going to just show it.  One commit at a time.
