Sorry to carry the bad news, but if this news checks out:
http://www.bighaber.com/haber/bitcoin-exchanges-offer-anti--money-laundering-aid-929817.htmlRather start to redesign exchanges, Mt.Gox is pretty much dead. This got to be a hard blow in the trust, the "aid offer" will be taken not only for bust drug dealers but to let the government stuck its nose on all BTC economy, from drugs and guns up to undeclared T-Shirt sales, making bitcoin the unsafer currency around.
So you expect an exchange that wants to be legitimate to not cooporate with authorities, no matter how "right" you may think it is as long as it is legal. Please explain how you expect it to work in the real world.
