Aggregating third-party capabilities and services drives Web 2.0 innovation. Developers must make trade-offs in quality of service and security to achieve rich and personalized experiences. The trade-offs threaten not only future innovation, but also existing experiences, business models, and everything that relies on mashing up data and/or functionality. Understanding and mitigating this risk is essential for all web applications. We present a prototype of an open technology for mashing up code while maintaining better process isolation, quality of service protection, and security. This will foster more efficient cross-browser development, increased mash-up innovation, and new third-party extensibility models. Join us as we discuss and showcase the architecture and invite you to get involved.Scott IsaacsDragos ManolescuDragos Manolescu is Senior Program Manager at Microsoft Live Labs, a confederation of engineers and scientists working on advancing the state-of-the-art in Internet products and technology.
