Could someone kindly give a status update on when will we have a real-world, usable CoinJoin (besides the implementation on Blockchain.info)? This thread is huge, and I'm sure many casual readers would like to see a tl;dr to learn will this result in a usable client soon, or what's the plan?

I found the thread when reading this article from 7 months ago. What has happened since?
