According to an article on MacCentral, a service called File-Cash is going to debut on June 1 that will use P-2-P technology to sell legitimate copies of music from 100 indy record companies to end users. The system supposedly makes use of encrypted Digital Rights Management technology to ensure appropriate use, but little information is available at this time.

Here's the kicker, the service will pay users when another user buys a tune downloaded from their hard drive.

The service is supposed to be cross platform on debut.
