twiboot-proxy for Arduino IDE/TWIBOOTm328p

This is not an issue but just a remark.

You might like the "twoboot-proxy" which allows to use a leonardo to bridge between the Arduino IDE and a atmega328 based twiboot device:

Thanks for the info. I've recently re-implemented my butterfly protocol bridge and integrated it into ispprog (https://github.com/orempel/ispprog). Currently it can only be used with multiboot_tool (https://github.com/orempel/multiboot_tool), but writing a patch for avrdude should be trivial (use 'I' command instead of 'P' command to enter programming mode).
