This has to be done when the controllers are connected initially, and if a controller has to be reconnected for some reason (e.g. it runs out of batteries). I don't know of any userspace tools that would make this easier to automate, except maybe a shell script, and I'd probably still need to run it manually. Both the Sixaxis and Xpad drivers appear to implement something similar, so perhaps a higher-level "player number" mechanism that works with all controllers would be worth looking into. This could in theory be done with a userspace daemon too (or a udev hook). As it is right now, I still think implementing it in the wiimote driver is the best method to keep it consistent with the rest of the drivers without having to install additional userspace tools. Thanks
