We are actively working on a multisig scheme where advertisers won't need to trust us with the money and we will only act as a pure middleman, signing transactions when the campaign is completed. The scheme is relatively well know at the present stage of Bitcoin development, but it still takes some time to implement right. We ourselves are not interested in holding other people's funds, it's dangerous.

On the other hand, if you DO have a way of providing such penalties in a cost-effective way, this concept would have more potential... and the only solutions I can think of still need more technology infrastructure to be developed.
