Anyone have experience with Everbanks worldcurrency access deposit account? (Foreign currencies for us citizens)

Seems like a great way to invest/access other currencies from the US without being a citizen or having a foreign bank account.

I see that the EverBank WorldCurrency Access Deposit Account lets you hold foreign currency, switch back to USD and is FDIC insured.

Would this be a good way to diversify some funds against the US dollar? In case the USD crashes?
