Considering the maximum possible profit, the broker's fees and margin maintenance would overwhelm any possible gains. Possible losses, of course, are unlimited.
No one reasonable is going to try to short a stock like BCCI which is bumping along it's all time bottom. There is a school of thought that says you can short penny stocks at the top of a penny-panic run, and it will be easy to cover as the company begins to flood shares into the market on the inevitable price crash. But you would have to do it through an illegitimate off-shore broker. In any country with reasonable security regulation, it would not be possible.
