Abstract: The invention relates to a method, a computer program and a computer network for real-time data sharing. The computer network (20) comprises a plurality of computers (2, 4, 6, 8, 12, 14, 16 and 18) interconnected by means of a network (3). Each computer comprises a conferencing environment (2a, 4a, 6a, 8a, 12a, 14a, 16a, 18a). The computer network comprises a data transmitting unit 3, notably a suitable server, arranged for providing the data to the computers. Each computer (2, 4, 6, 8, 12, 14, 16, 18) may further comprise a dedicated data transmitting unit (2b, 4b, 6b, 8b, 12b, 14b, 16b, 18b) for enabling autonomous data uploading and data downloading. Each computer further comprises a computation means (2c, 4c, 6c, 8c, 12c, 14c, 16c, 18c) arranged for parameterization any local change in the data. The parameterization results are generated locally and are transmitted when the corresponding computer enters a sending mode.
