The ROS velodyne driver has been around for several years an an experimental stack, mostly used in-house at the University of Texas, Austin. http://ros.org/wiki/velodyne There is interest in supporting more device models, so it is time to do a formal API review to ensure we meet everyone's requirements. I created a review page here: http://ros.org/wiki/velodyne/Reviews/2012-02-02_API_Review If you are interested, please add your name as a reviewer and post your comments and questions there. --  joq
