Hi, I managed to pathc avrdude myself (with patches from the japan site) to replace bootloader on my arduino duemilanove (ATmega328P) because I wanted to try adaboot.
Will be great if burning bootloader using ftdi bitbang mode will be supported out of the box within the arduino ide.
Maybe with a collaboration with avrdude developers will be even more great if that feature will be included directly in avrdude and not as a specific patch for arduino ide.
