There was some recent ros-users discussion about extending the camera_info_manager by substituting the camera name and perhaps other parameters in the URL string. This seems like a good idea. Getting it reviewed, coded and documented in time for Electric Emys will require fast action, however. So, I would like to get everyone's comments in time to close the review on Monday June 13th. Please add your name and comments to this API review page if you can participate: http://www.ros.org/wiki/camera_info_manager/Reviews/2011-06-06_API_Review All ROS users are welcome to participate. --  joq
