Hi Jerry, this looks pretty interesting to me since lately i dont have time to contribute in steemit , so would like to rent my power. 2 questions though:

1. Is there any key sharing that needs to take place?

2. If you are the one borrowing power, if the cost is higher than your balance , what happens? Or is it always a percentage of your profits?

Thanks again for the post, it put me into some thinking now!
