The open Web is a great platform for rich applications. It would be even better if it had additional capabilities to ease discovery, acquisition, installation and use of apps, while also enabling monetization for developers. We designed and built a prototype of a system for open Web apps: Apps built using HTML/CSS/JavaScript that work both on computers and mobile phones, have many of the characteristics that users find compelling about native apps and provide developers with open and flexible distribution options. - John LeMasney
