AB: Increasingly large collaborative teams, geographically distributed, coupled with experimental and numerical data sets whose size appears to increase exponentially, demands new solutions to ease data analysis, visualization, and manipulation in a transparent manner. Rather than concentrate on where and how the job gets done, users should be able to interact with their data without concern for the underlying hardware, system load, or resource availability. We address this problem through a a unique and flexible architecture, based on the NaradaBrokering (NB) middleware application program interface (API) (http://www.naradabrokering.org, [1]). We aim to support collaborative real-time remote visualization, data analysis, and video creation with an emphasis on simplicity of use. NB connects clients to services through the use of topics, rather than IP addresses and hostnames. The flexibility of this approach makes it possible to easily incorporate logging systems, redundancy, fault-tolerance, asynchronous communications, and collaboration as additional web services into the system. Furthermore, it becomes possible to insert additional services into the system such as databases and storage archives. After describing a prototype system within the context of Web-IS [2-3], we will demonstrate fault tolerance with respect to the faulty nodes in the NB network and with respect to the visualization servers, and the ability to share data.
