AdSense API Launched for Developers

Developers with 100,000+ daily page views and users contributing content will now be able to offer a "one stop shop" for their content creators to sign up for AdSense while allowing developers to integrate and optimize their AdSense ads for them. And while doing so, developers could be eligible to earn not only a $100 referral bounty, but also a 15% revenue share which would be paid directly by Google.

For more details, see the AdSense Blog, AdSense API home, or JenSense.
