Did you ever finish the 2.0? I only see a beta on your site.
A few requests, actually . . .
1) A cancel button. If it doesn't connect for whatever reason, it freezes.
2) Remembers the last baud/COM and .hex folder settings used.
3) An update COM ports button.
4) Change 'Axon II' to 'Axon, Axon II, or Axon Mote'
side notes . . .
I couldn't get your software to bootload an Axon using bluetooth. As soon as I reset the Axon (using the reset pin, not a power reset), the bluetooth disconnects the serial connection (using bluesmirf by sparkfun). It's as if the bootloader is sending a serial command that tells the bluetooth to disconnect. Not sure if this is fixable, though.
