Stamp did it, in quite a short time it seems. Gox can do that too.
We'll be back to where you can't get fiat money out of Gox (because they do not physically have money - or do they, after manipulating the market like that, BTC can be bought as we speak from their own traders), but you can get BTC out.
Let's see how many of those BTC migrate to Stamp / BTCe for a quick buck - I could get away with a couple of days delays in wire transfers for 100% profits...
