Bitpay does, I have heard in an interview where Tony Gallippi said they have Bitcoin on their balance sheet.

There are lots of these now, some that come to mind are;

Credit cards are a broken payment system which are susceptible to fraud.  I am not sure why topics like this come up from time to time as the user does not care if their credit card transactions settle in EUR, USD, JPY, Bitcoin or what ever. 

Bitcoin is a superior electronic payment system to credit cards, it is completely stupid to cripple it with a marriage to the credit card system.

It is Mount Gox...  just like its Mount Everest.

This is not the case, depositors at the bank become first in line as creditors to re-captialise the bank, its called a bail-in and lots of people in Cyprus got angry about it!

One flaw you maybe missing in this is that any Bank/Credit Union requires an upstream bank to provide clearing/settlement.  Only the main banks can provide that and if they refuse to provide you settlement services due to associations with bitcoin then your bank/credit union is rendered useless.

In New Zealand the Internet Party internet.org.nz has been launched in conjunction with Kim Dotcom.   In part of the manifesto it lists Digital Currency (aka a crypto currency) as one of the action agenda's.

LOS ANGELES (AP) — The man Newsweek claims is the founder of Bitcoin denies he had anything to do with the digital currency.

In an exclusive two-hour interview with The Associated Press Dorian S. Nakamoto, 64, said he had never heard of Bitcoin until his son told him he had been contacted by a reporter three weeks ago.

Reached at his home in Temple City, Calif., Nakamoto acknowledged that many of the details in Newsweek's report are correct, including that he once worked for a defense contractor. But he strongly disputes the magazine's assertion that he is "the face behind Bitcoin."

Since Bitcoin's birth in 2009, the currency's creator has remained a mystery. The person —or people— behind its founding have been known only as "Satoshi Nakamoto," which many observers believed to be a pseudonym.

No, I was just commenting on maaku's trustless exchange design.

You still have to "trust" the person who made the sworn statement.   Do you trust an entity setup whose purpose is to defraud you by making false sworn statements?

That also does not work as a bank requires clearing and settlement, and upstream banks which has this ability are few and are tightly controlled by the countries central bank.  So its possible to incorporate a bank but it is useless if the upstream channels refuse to service you.

Due to privacy laws in countries if a 3rd party asks a bank about someones account they will tell you they can't disclose such information.  Even if you could ask the bank you have to "trust" the bank is telling you the truth.

systems security and host security are also different as it covers business systems and processes and not just a server.    In yout reddit post you say the following about a gateway;

As shown by gmaxwell/nullc, you can do zero knowledge proofs of summation of user balances to get clear knowledge about their liabilities, and they can publish bank statements to show that they have enough assets to cover a bank run.

How do you determine if a gateways published bank statements are legitimate or forged?

The difference is your talking about auditing solvency which is a good thing, but this forum thread is about auditing systems security which is another matter altogether.

From your reddit posting;

Users deposit bitcoins and other crypto assets by means of an audited gateway or pegging mechanism.

It seems your plan requires auditing too.

In the credit card world there is PCI DSS.  However even companies which are compliant to this standard get hacked from time to time and news of this hits the media of the thousands of credit cards stolen.

Christine's concern about bitcoin being a tool for money laundering and tax evasion is really a concern that technologies like bitcoin threaten the traditional banking systems protected monopoly they have on the mass money laundering and tax evasion they conduct themselves.   A protected monopoly is very profitable and the bitcoin invention undermines that monopoly.

The gox is still not as bad as a Cyprus style bail in!

The problem is you send FIAT to gox's bank account, but I doubt you will see that as a balance in your goxed account anytime soon!

I guess this the reason why Max Keiser left France and moved to London?
