Arduino I2C Slave to hold I2C bus when buffered writing to EEPROM

Using Arduino Networking, Protocols, and Devices

This is about an Arduino as I2C slave, and I write data to the EEPROM of the Arduino via I2C. The Arduino simulates an I2C EEPROM.

The page write is something very close to the buffered write to EEPROM.

But implementing it, seems not possible.
