XTV: a framework for sharing X Window clients in remote synchronous collaboration

XTV is a distributed system for sharing X Window applications synchronously among a group of remotely located users at workstations running X and interconnected by the Internet. The major components of the system are designed and implemented in such a way that make them reusable in other collaborative systems and applications. A description is presented of the fine technical details and knowledge required to understand and replicate the work which went into developing XTV. The following concepts are discussed: interception, distribution and translation of traffic between X clients and display servers; regulation of access to tools using a token passing mechanism and reverse-translation of server traffic; and accommodation of systems with different architectures which may have different byte orders for integer representation.<
