A method, system and apparatus for use in computer-aided design, computer-aided manufacturing, computer-aided engineering and product lifecycle management. An efficient, non-centralized communications framework makes “synchronous” collaborative design possible. Users are resident at workstations that are connected in a peer-to-peer arrangement.
