title: What is the range of bluetooth and is it strictly 1:1?
body: <p>Does anyone know what kind of range can you get from the iPhone
  bluetooth? Also, would the connection be strictly one to one? I know you
  can choose from a number of peers to connect to but once the connection
  is established, it seems you can only transfer data between one peer? So
  basically, is it possible to create some kind of "multiplayer" experience?</p>
