....previous piece of work that has addressed all of the issues that motivated our work. However, there are several relevant projects that served as inspiration, amongst which are Media Spaces [4] 5] groupware toolkits to facilitate collaborative application authoring like Groupkit [6] and SCOOT [7], and the work on capture, indexing and playback tools done at Xerox PARC [8] 9] Our mobile paradigm goes further than Teleporting [10] in that it does not rely on any windowing paradigm and in contrast to Migratory Applications [11] it does not imply the building of monolithic applications. We ....

These X based systems work, work coupled with the Window Server on an workstation in one of two ways (see Fig. 2.1) Under the first approach, followed ....

....(so as to handle other media streams such as audio) discourages the use of existing SWSs wrt the requirements for the interactive delayed sharing of a workspace. Application dependent record and replay of a workspace has recently been proposed in the CECED system [24] through its SCOOT project [23]. The SCOOT project proposes two approaches to replay of a session. The first approach centers around periodical recording of application state snapshots. The second approach logs invocations to object s methods. This is very similar to our replay by re execution approach. However, the SCOOT ....

....offer fine grained audio synchronization support. The ideas presented in this paper can be used to extend these systems to include synchronized audio support. Toolkits and application specific prototypes represent application dependent approaches to session capture and replay. The Scoot toolkit [9] proposes two approaches to capture and replay of interactive sessions. The first approach logs periodical application snapshots. This choice results in coarse replay progress feedback and limited synchronization precision. The second approach logs method invocations to log aware objects. However, ....

The multimedia and computer supported collaborative work research communities have developed an array of toolkits and techniques for collaborative work. Examples include DAVE [125] SCOOT [36], 38 GroupKit [143] the Continuous Media Toolkit (CMT) 144] and VuSystem [112] We briefly describe CMT and VuSystem since their approaches are most similar to ours. CMT is an object oriented multimedia toolkit that allows objects to be mixed and matched into arbitrary applications. CMT ....
