“…The DAVE approach does not require tile purchase of special cable plant or exotic hardware and supports both multicast and broadcast of data thereby increasing interoperability and portability. AT&T's Rapport [ 1] appears to somewhat address the issue of media independence through software abstractions. Rapport, like the Touring Machine, is based on analog transmission.…”

“…DAVE was implemented using standard UNIX workstation components and traditional IP networking for all interhost communications. In the past, distributed environments (e.g., Rapport [ 1]) relied on means such as coax cable or telephony rather than IP for media transport. Our goal was to leverage off existing workstation and network infrastructures to increase the level of interoperability and availability.…”

This paper presents a model being used for the development of distributed multimedia applications. , The Distributed Audio Video Environment (DAVE) was designed to support the development of a wide range of distributed applications. The implementation of this model is described. DAVE is unique in that it combines a simple "plug and play" programming interface, supports both centralized and fully distributed applications, provides device and media extensibility, promotes object reuseability, and supports interoperability and network independence. This model enables application developers to easily develop distributed multimedia applications and create reusable multimedia toolkits. DAVE was designed for developing applications such as video conferencing, media archival, remote process control, and distance learning.

“…Different architectures are possible when building a system for shared use of applications. In [1], this is discussed for desktop application sharing, but some of the results are applicable to the area of web application sharing. Our solution uses the "replicated execution" approach, but a "single-site execution" approach is preferable and an area for future work.…”

When people collaborate remotely, the WWW is part of the shared resources they use together. However, web pages do not offer support for collaborative interaction such as viewing or influencing another user's browsing session -additional software needs to be installed for these features. In this paper, we present UsaProxy 2, an HTTP proxy that allows the same web page or application to be viewed and used in two browsers at the same time, without client-side software installation. This includes a visualisation of the remote user's mouse pointer, scrolling, keyboard input, following links to other pages and more. Our open-source proxy modifies HTML pages before delivering them to the browsers. The added JavaScript code provides session monitoring and shared browsing facilities. We conducted an experimental evaluation which shows that our approach works for different scenarios, such as shopping online and exchanging ideas on what to buy. The user study showed that our approach is accepted and liked by users. Combined with audio or text chat communication, it provides a very useful tool for informal, ad-hoc collaboration.

“…In attempts to deal with problems resulted from the centralized architecture, some later systems adopt the replicated architecture in which each collaborating site has an instance of the shared application. Examples include Dialogo ), MMConf (Crowley et al 1990), VConf (Lantz 1986) and Rapport (Ahuja et al 1990). In contrast to the display broadcasting technique used in centralized systems, these systems adopt the event broadcasting technique, where input events to the local site are broadcast to all remote sites.…”
