The National Virtual Observatory (NVO) will provide on-demand access to data collections, data fusion services and compute intensive applications. The paper describes the development of a framework that will support two key aspects of these objectives: a compute engine that will deliver custom image mosaics, and a "request management system," based on an e-business applications server, for job processing, including monitoring, failover and status reporting. We will develop this request management system to support a diverse range of astronomical requests, including services scaled to operate on the emerging computational grid infrastructure. Data requests will be made through existing portals to demonstrate the system: the NASA/IPAC Extragalactic Database (NED), the On-Line Archive Science Information Services (OASIS) at the NASA/IPAC Infrared Science Archive (IRSA); the Virtual Sky service at Caltech's Center for Advanced Computing Research (CACR), and the yourSky mosaic server at the Jet Propulsion Laboratory (JPL).
