Now or later. It would be reported to IRS, so being a financial commoner, I don't know a loophole to get around this :(
Well, some people would think that if you took your money now, you don't have to settle up with the authorities until April 16, 2011 or the Fall of 2011 if you filed an extension. By then, the IRS, as we know it, may not exist. But that's just silly thinking...leave your money in the IRA...nothing bad is going to happen.
Or you could withdraw the money, don't withhold for taxes, and leave the country (you could hide the cash in your underwear, nobody thinks to check there). Change your name, dye your hair, gain or lose 100lbs. And you're home free.
