I know the iPod Touch has no bluetooth.
But can't we make something for it like this:

Possible apps would be:
  • Share your Music with Bluetooth
  • TomTom for iPod Touch
  • Wireless headset for iPod Touch
  • Etc.

I think there will be a lot of cool things we can make using bluetooth for iPod Touch.

Is this possible?

P.S. as you see on the picture the dongle is very,very small so it can fit in a iPod dock connector.
