I was recently alerted about the Data Mining Case Studies Workshop and Practice Prize:
The Data Mining Case Studies Workshop and Practice Prize was established to showcase the very best in data mining case deployments. Data Mining Case Studies continues into its third year, to be held at KDD2009. Data Mining Case Studies will highlight data mining implementations that have been responsible for a significant and measurable improvement in business operations, or an equally important scientific discovery, or some other benefit to humanity.
The site states a final submission deadline of April 8th, but one of the organizers told me that they are willing to offer extensions. Further details and contact information are available at http://www.dataminingcasestudies.com/.
