Re: CoinShuffle: Practical Decentralized Coin Mixing for Bitcoin
Quoting myself:
Regarding JoinMarket, I'm not sure. It seems that it is not so sophisticated as CoinShuffle, but that's rather a first guess. Is there a technical description of how it works under the hood? I can only find descriptions of how to use it.
Also, JoinMarket seems to understand the problem as a economic one and someone is gets fees for enabling the mixing. CoinShuffle is different here, the participants just pay the single transactions fee for the CoinJoin transaction, which is very low and can even be split among all participants. But there is no party that gets an additional mixing fee (on top of the transaction fee).
I've just started a collaboration with Kristov Atlas. We will write a BIP draft including a more detailed, development-oriented specification of the protocol including all the nitty-gritty details. We also plan talk to wallet developers and I will definitively write some code as soon as a reasonable version of the BIP is there. Contributions and collaborations are welcome in all stages, of course. 
We'll provide more information, including a mailing list, soon.Regarding JoinMarket, I'm not sure. It seems that it is not so sophisticated as CoinShuffle, but that's rather a first guess.

Hi TimRuffing and Kristov Atlas,
sorry for having missed this last post somehow in my other comment.
I'd really love to help with such a reference implementation, with a wallet-integration-perspective. At Mycelium we see fungibility as a very urgent issue and having worked on a JoinMarket Proxy myself, I feel like JoinMarket might be a dead end precisely due to what CoinShuffle claims to solve. At least from the Wallet-perspective.
For this, I wonder what harm would be done if the current state of implementation was already public for others to tinker with.
I'm particularly interested in ease of integration with wallets and my focus in Joinmarket there was to not share private keys with the mixing module, which in the link above was a server but for mobile wallets could be an app working like the orbot TOR proxy locally on the device.
