Have a driver (in a module) that Um, let's not. This really isn't something the kernel needs to solve here at all. There's a viable userspace solution. I see that the discussion of something finally slightly technical (as opposed to just compliance BS) has nerd sniped you a bit, but keep in mind what the actual overall picture is. This isn't something that needs to be done. My little CUSE thing (which I'm happy to develop out a bit more, even) has the intent of fulfilling a compliance checkbox and nothing more. Jason
