I am working on a little project I am open sourcing that I think would make a good example. It is currently based on a simple LED example but uses a Node.JS extension to allow for remote access via web services. I did this with the idea in mind that I would eventually use a wifi chip instead of the computer, but might be good for some people the way it is....
P.S. I would be more than willing to make this an example with some guidance.
