Bluetooth --> Wifi

Wouldn't it be useful if we were able to access the internet on our mobile phones in Wifi Hotspots. My idea is that we have some sort of device (like a wireless router) that takes in bluetooth signals and converts these into wifi and then sends them onto a wireless router. Obviously the process would be easier if the bluetooth convertion occurred within the router itself. If a wireless router had a bluetooth antenna attached then it could also connect with bluetooth phones. The signal would be processed into a web request which would be executed. The result of the request would have to be processed into a bluetooth signal again and transmitted to the device that sent the request.

I think devices that encourage multiple devices to perform the same action are the next in thing for our society. It is slightly different to what we imagine "Convergence" to be since that is about stuffing as much as you can into one device. What I suggest here is a way for these multiple devices to interact, though they may be on completely different technologies/protocols/implementations.
