Yeah! You can also use it for p2p loans. Make a 2 of 3 bitpac between a borrower, a lender, and a neutral third party. Have the borrower put some collateral in the bitpac address and have the lender send him some USD. If the lender pays off his loan on time, the borrower or the neutral third party can cosign with the lender to return his collateral to him. If not, the lender or the neutral third party can cosign with the borrower to pay it off using part of the collateral, then send the remainder (if any) back to the borrower.

What's also cool is that the neutral third party doesn't even need to know they are involved unless there is a dispute. You could use Marty Bent for example and only ask him to intervene if your counterparty acts unfairly.

The same principle applies for stuff like futures contracts. One person goes long and is supposed to get some money if bitcoin's price rises by a certain date. The other person goes short so he takes the opposite gamble. If both parties cooperate, they can cosign together to release the funds to the winner. If either one is a sore loser and won't sign to release the funds, the winner can contact the neutral third party and ask them to intervene.

But unlike with DLCs, the neutral third party doesn't need to run a server, or even know they are participating.
