Is a full working version of coinshuffle being developed? The research site says the current version was just a proof of concept for testing and not usable for real coins.

Amir says it's being worked on for Dark Wallet.

I thought they were implementing CoinJoin instead.
EDIT: true, Amir confirmed that: https://www.reddit.com/r/Bitcoin/comments/2ijsw1/the_coming_of_darkwallet/cl2qow6

On the other hand, I see a problem with CoinShuffle. The participants are supposed to sign their messages "with their addresses"; this assumes that the inputs they provide were paid to standard P2PH addresses, but they cannot use outputs sent to P2SH (those starting with a 3, e.g., "multi sig" addresses). Participants could still be required to reveal their script and then sign their handshaking rounds with a key contained there (if there is any).

Darkwallet's webpage still lists coinjoin as their shuffling method. Anyone know the status of Dark Wallet's coinshuffle implementation or any other implementations?
