Drupal's Payment API -- http://drupal.org/project/pay -- is a simple, flexible and pluggable payment transaction handler for Drupal. Advantage Labs has recently extended the functionality of the Payment API and built a crowdsource pledge-funding feature using contributed Drupal modules.
The Payment API module gives you single-click donation form creation capability allowing simple cartless payment solutions in Drupal. Recently launched using the same tools, the Cedar Seeder's (http://www.thecedar.org/seeder) Kickstarter-like functionality displays the greater creative potential for Drupal-based funding initiatives.
Barry Madore from Advantage Labs will walk you through the modules and functionality used in building the Cedar Seeder project. He will also talk about the goals for future development and community uses for the tools involved.
