Seems like this is the same scenario that we all missed out on during the ETH/ETC fork.
Consider the scenario
Alice shorts ETH by borrowing 200 ETH from Bob and selling it to Carol
Carol, who used her own BTC to buy 200 ETH in the spot market, withdraws all 200 ETH to her Mist wallet
Alice now owns Carols BTC
BCC Hard Fork occurs
Alice now receives BCC
Alice closes her short by selling her BTC and buying back ETH and sending it back to Bob.
OR you don't even have to take a trade
Alice places a bid to buy ETH at 0.0001 ETH/BTC and sends it to the market
During that time Alice borrows BTC from Carol
BCC Hard Fork occurs
Alice now receives BCC
Alice cancels her ETH order
Carol gets her BTC back from Alice with interest
PS, this is highly speculative... do it at your own risk.
