If it's as tempremental as bluetooth then forget it
In my experience bluetooth mice and keyboards constant require reparing to make them work, they also suck batteries.
Wireless mice and keyboards can be bought now that operate on 2.4GHz so they work from a decent range
they require no setup you just plug in the dongle and you're off
One dongle supports a keyboard and mouse
the dongles are tiny, they can be left connected to a laptop full time without fear of damaging the USB port
most importantly batteries will last a couple of years in a keyboard and over a year in a mouse. Bluetooth is good for handsfree in the car, that's the market these people should be aiming for.
