    We could create a sysfs attribut named ir_config. For each config file
    you copy to it it creates a new input device. The config files have
    lists of map this protocol, device, command tuple to this key. When a
    remote button is pressed the raw codes are fed to the in-kernel
    protocol engine. That engine turns the raw codes into tuples. Tuples
    are matched against the configs that have been loaded until a hit is
    found. If no hit they get sent out the catch-all device.

    Most remotes send out unique codes, they have to or they would turn on
    unintended devices.
