Is it possible to network several arduino together without the need for extra shields & a router? Something like... using pins 2 through 4 to set up a daisy chain of devices, each with their own address. If it is possible I'd love to know how. Thanks!

I2C for short distances only.

For longer distances an RS485 bus is one option, but it requires a chip to convert the Arduinos serial signal to RS485 signals. This chip is cheap, and fairly easy to implement.
