What kind or wireless interface are you looking for? WiFi? Bluetooth? something else?http://www.clasohlson.co.uk/Product/Product.aspx?id=164641152
is a £60 system where a gauge measures power consumption in your fusebox, and wirelessly transmits data to a display unit, which may connect to your computer by USB.
I would LOVE a similiar system, where a 8/0/0 (or even a 8/8/8) would sit stand-alone (powered by a couple of AA batteries or somthing) and transmit wirelessly to a InterfaceKit Controller connected to the computer by USB, transparent to the programmer and application. If the easiest setup would be to make the actual USB connection the wireless one, fine, but make it easy to put an IK where there is no power supply and no USB or Ethernet cables..
