Sturle, can you explain the logistics of such a trade? I would also be interested in buying up discounted mtgox CDSes (that's essentially what they are), if I could be confident that the trade could be accomplished securely. I don't think you can make Mtgox codes anymore? How are you going to transfer the Mtgox balance?
You can transfer BTC between MtGox accounts. The sender can withdraw to the deposit address of the receiving account. The transaction will be handled internally, and the transfer will not enter the blockchain. (Unless you check "Open Transaction". Don't do that.)
