In the recent years advancements in the development of Networked Virtual Environments (NVEs) can be observed in many domains. Although this technology is available, it is still a challenging task to design and produce these virtual worlds. To ease the creation of such environments the inVRs framework was developed. Besides this also grid environments have advanced from traditional batch processing systems in the area of scientific computation. Nowadays highly responsive and interactive grid jobs can be supported: Real-time Online Interactive Applications (ROIAs) constitute a potential domain. The edutain@grid middleware provides an approach to use the advantages of Grid technology, like Virtual Organisations (VOs), dynamic resource allocation, etc. and additionally fulfils the requirements of highly interactive real-time applications. The rtfOdrom application acts as a prototype application to demonstrate the interconnection between Grid computing and Virtual Reality.
