Given tc's edits above regarding additional charges for transferring out of AWS I'm starting to change my mind. I still can't believe amazon would ever end up charging north of $20k for a 3TB retrieval but it seems the intended use-case (as enforced by pricing) would be write-once read-never! Other use-cases are possible but as others have noted you would want to be very careful how you go about setting it up to avoid getting some ugly charges.
