The concept of document-conferencing is to share a piece of paperwork in various locations. The document is put in a special projector, which allows users in different places to make changes using a pen-like device. Polycom's showStation is T.120-compliant, which supports data conferencing via standard phone lines, ISDN (integrated services digital network) and local area networks. The equipment can be connected to an audioconferencing system and a laser printer. Those without the projector can join the conference by installing special software on a connected PC. But the Asia-Pacific general manager of telecom services integrator Darome, Ian Wells, said today's document-conferencing only supported black-and-white image sharing and transmission of colour would add pressure to data traffic. Last month Darome launched Net Conferencing, which enables Internet users to log in to the Darome network to share documents created in Windows with others through a standard Web browser. The new service is made possible by DataBeam's neT.120 conference server, a software server for hosting multi-location conferences on the Internet and corporate intranets. Instead of a hardware provider, Darome offers the bridging services for multi-point teleconferencing (audio, video and document) by co-ordinating the different parties, hiring out facilities and providing services such as audio and video-tape recording. Mr Wells said the number of people who could get involved in teleconferencing was virtually unlimited. 'Companies can broadcast their annual general meeting to anywhere in the world and direct communications between senior executives with shareholders,' he said.
