AZARDI is designed for the controlled channel delivery of interactive content. It is optimized for specialist vertical channel content rather than being "just another reader". This demonstration starts to demonstrate what is possible.
You can download EPUB3 UNLEASHED and AZARDI 7 here.
One of the motivations for producing this was to show that the core technologies can deliver a lot more than anything that is in the market at present, and it can do it easily and cost effectively. The IGP:FoundationXHTML that is packaged into an ePub3 here can also be delivered as a Web Site and WebApp (with the exception that Android doesn't handle SVG!)
