How to create a selfcontained Wireless Network

This was a challenging project, put upon me by a friend and colleague who needed a web server that they could carry around with them. The goal was to have it accessible by wireless devices such as mobile smart phones (Android, Blackberry and iPhone etc), iPods, Playstation portables, and Nintendo DS'; without the requirement for either the server or the devices to be connected to the Internet.

For the purpose of a presentation and demo, the web server would contain a small mobile website that the devices could view at any location that the demo was taking place, and interact with, without having to worry about having Internet or even local network connectivity.
