      I don't think so. Those mentioned protocols address different needs than Bluetooth. For example, Zigbee is targeted to those sensory applications that need to transfer data with a very low duty cycle. WirelessUSB tries to do what it's name suggests, replacing the cables in a USB connection. On the other hand, Bluetooth supports multiple transfer profiles. For many applications, it's serial profile excells as many developers are quite familiar with it and have used serial ports in PC or micros for years.

      Regardless of the intentions the inventor has in respect to 802.11x technology there are some rather significant reasons that using 802.11b, g or a for keyboards and such just doesn't makes sense.

      Addressing
      ----------

      802.11x uses standard 802.3 addressing and is an extension of wired ethernet as such. Thus any 802.11x device will receive a standard IP address.

      Compare this to bluetooth where devices are connected in a piconet using a master/slave model.

      The piconet model makes so much more sense for keyboard/mouse or other device model where a simple data transfer is needed that has no reason to be routed anywhere. Otherwise you are turning the master device into an access point to a network and making it do a job better suited for a pure access point. If IP traffic is needed then a higher power access point makes SO much more sense to increase range.

      Transfer speeds
      ---------------

      Bluetooth works a 1MB transfer speeds where 802.11x operates at 11MB and up. I can't think of a single instance where a bluetooth device would be better suited for 11MB or higher transfer speeds. How much data does a keyboard push? Is your mouse a data hog?

      The only thing I can conceive that you might want higher transmission speeds at close range would be high quality video and in that case you would be better suited to use a wired solution anyway at close range. Interference could cause a noticable lag in video.

      Utility
      -------

      The utility of 802.11x is not one that is conducive to simple input devices such as keyboards or mice. To make a comparison does it make sense to rent a bus to drive to the beach with your two friends or rent a standard car/SUV type vehicle? Sure, you could toast a slice of bread in an oven but it makes so much more sense to use a toaster.

      To use 802.11x devices to transfer something requring a fraction of the speed is a waste of spectrum.
