Remote participation is a key success factor for worldwide organizations and video-conference is an important aspect when laboratory collaborators are geographically dispersed.Several tools for video-conference are available worldwide. However, there is a need for a default integrated set of tools which provide all the needed features for remote participation between cooperating laboratories. Moreover, laboratories currently use different video-conference tools to communicate leading to a non-compatible method among them.OpenMeetings is open source software which provides video-conferences through web-browsing. It is operating system independent, requires no computer installation providing easy integration with already existing tools and customization of requirements.This paper intends to give an OpenMeetings overview as a video-conference application between worldwide laboratories and to demonstrate its integration with the European Fusion Development Agreement (EFDA) Federation authentication and authorization features. EFDA Federation is a multi-organization security infrastructure, whose purpose is to provide sharing and provision of a wide set of resources so that authenticated users may access them in a transparent and secure mode. This infrastructure is based on a distributed security technology called PAPI (Point of Access to Providers of Information).OpenMeetings can be a valuable EFDA Federation resource and a good approach as a method to provide a worldwide laboratory video-conferencing application, based on standard browsers.
