//slave reflasher code -- it can reflash an I2C slave over I2C!  You must set fuses and install twiboot:
/*
the commands would be something like this for Atmega328p
.\avrdude.exe -c usbtiny -p m328p -U lfuse:w:0xC2:m -U hfuse:w:0xD8:m -U efuse:w:0xFD:m
.\avrdude.exe -c usbtiny -p m328p -U flash:w:twiboot.hex:i
