I have a little app called "bluetooth file server" but havan't used it yet.... maybe I'm not sure how to use it... I'm not crazy about the interface.
Looks like yours may work better for the Droid.
At least it has a Help section that makes sense, and works off 3g for same network, and wi-fi to other networks..... thats more than I can say for the Bluetooth file server.
