Daisy Chaining Arduino Serial Connections
Over at the Geodesic Sphere they have come up with an idea using the UART feature and connected as shown in the picture. Its cheap, lightweight, easy to implement and doesn't need special connectors.
The fastest I have ever seen a UART operating at was around 110Kbits / sec so its not as swift as Ethernet or some of the other options and its definitely one way only but if that's all you need this could be an elegant solution.
