hi, The Fuerte SIG on inter-process communication is looking into improvements to ROS communication over WiFi. The first thing we need is an understanding of users' requirements. If there's something you want or need, please add it to this page: http://www.ros.org/wiki/fuerte/Planning/IPC/WiFiNeeds The multi-master SIG is also discussing some of these issues (http://www.ros.org/wiki/fuerte/Planning/Multimaster). We'll be sure to share results and coordinate work. thanks, brian. -- http://brian.gerkey.org
