I thought they are only in the USA but it is already in Europe.
The last bastion of privacy is Namecoin.

This would just as easily be applied to Namecoin as Bitcoin. That said, I think Zerocoin and CoinJoin would prevent this system from being effective.

Thanks. I thrust your evaluation and if it is positive it is a good sign for me.

Another privacy enhancing technique proposal 'Merge Avoidance' compared with CoinJoin:

Updating with new privacy technologies for cryptocurrencies:
SharedCoin:
based on CoinJoin
http://sharedcoin.com/

How long do shared transactions take?
Between 30 seconds to 5 minutes depending on the number of iterations.
Is there a maximum transaction size?
The maximum transaction size is 50 BTC.

2 new developments which might possibly be useful for us in the future:

Zerocash: https://www.youtube.com/watch?v=FXU65XsLiFk
Darkcoin: http://darkcoin.io/

Anyone seen the AppeCoin proposal?

https://bitslog.wordpress.com/2014/04/2 ... ncy-draft/

It attempts to provide better anonymity than CoinJoin, particularly with respect to correlating payment amounts, while using much simpler crypto than Zerocash (and without needing a trusted third party to initialize the system).

As I've been saying for quite a while, I think that until the dust settles, we shouldn't commit all of our users to a specific anonymization method. If sidechains end up happening, then namecoins could be moved to a Zerocash or AppeCoin sidechain (depending on which one the user trusts more), and only transferred back to the Namecoin chain for purposes of paying for names. While timing leaks are possible with a sidechain transfer, that's already the case for name transactions, and (I think) is more robustly fixable with better client behavior.
