Is there a way that you can connect multiple slave Arduino's with one master Arduino using the ethernet shield? Doesn't the connection between two Arduino's use the common ground, RX, and TX pins.

What does the Ethernet shield have to do with I2C? Nothing, nada, zip, zilch.

No. I2C does not use the Serial pins.
