- We have a program called XT-Confer which provides an environment for writing CSCW
- applications under X-Windows. The program is the "glue" that binds it together,
- and it provides an API and data structures to enable "tools" to be written.
- It currently supports 10 tools, including text conferencing, shared editing,
- shared sketch-tool, shared shell, vote tool, shared calendar, and finally a
- "watcher" tool which enables arbitrary X-WIndows to be watched and "shared" with
- the other "delegates" in the "conference". All of the tools apart from the watcher
- are fully interactive, and support multiple users of a single tool. For example,
- the edit tool enables different users to have their own insertion points into a
- document.
- It supports floor control, as a layer above the tools provided by the core
- program. Tools are just notified when the floor changes. Floor can be either open
- or closed. Closed floor is when one user has control of the floor. Floor Control
- is on a per-tool-basis.
- Sharing is automatic, but the watcher tool is active (you choose what to share).
-
- It supports different views on a tool, for example when the floor is closed to
- you, many of the buttons on the tool will be greyed out. As another example, the
- text conferencing tool has a "private" coomposition area for each user, and a
- shared speech area.

- See the Proceedings of the 1992 European X Users Group Conference for a paper
- written by myself about XT-Confer. Also, contact support@xtel.co.uk for info
- about availability of XT-Confer, or contact me.
