I read that some were developing a commision module to Ubercart a while back. It's great with a revenue sharing module that enable you to provide the user with a commision defined by the admin, similar to Istockphoto.com. Does anyone know what happened to this and if some has already has posted this? I've been looking for this for a while, and changed from e-commerce to ubercart as this was planned. However, not much progress has been made publicly...
