Is it possible to network two Arduino's together?

and I mean via an ethernet shield. So they are both connected to a LAN (or even WAN) and able to trade information directly between each other?

Has anyone done this and are there any tutorials online please?

Thanks,

Have a look at my website, I made an example with arduino two way wifi communication

That is communicating via a webpage. I am looking for an example of two Arduino's communicating directly across a LAN, i.e. 2 Arduino's with an Ethernet Shield, both into network points on a LAN and send data to each other.

Same thing, just put the ip of the other arduino in instead.
