Here is a summary of the responses to my query on toolkits for building
groupware interfaces

------------------- S U M M A R Y------------------------------------------- 
It seems to me that Zloof's work on SBA/OBE (IBM, Yorktown Heights),
and any work on DBMS triggers would qualify, here.

The Slate system from Bolt, Beranek, and Newman grew out of the Andrew (CMU)
multimedia messaging system, and has explicit support for group interfaces.
Slate is distinguished by being, I think, the first commercial platform for
building groupware interfaces.

MediaSpace and Shared ARK at Xerox EuroPARC are two more experimental
groupware systems.

I've implemented a simple multi-user sketching tool that runs under BSD
Unix (TCP sockets, RPC) with X11R3.  The following is an extract from
its manual page:

XSKETCH(L)               LOCAL COMMANDS                XSKETCH(L)

NAME
     xsketch - multi-user sketching program for X11

SYNOPSIS
     xsketch [session-id] [X Toolkit options]

DESCRIPTION
     Xsketch is a multi-user drawing program for X  Windows  ver-
     sion  11.   It  has facilities for drawing lines, boxes, and
     text.  It has cut  and  paste  facilities  for  editing  the
     diagrams,  either on an individual element basis, or by rec-
     tangular regions or (blocks).  It also supports  the  saving
     and  loading  of  images to and from disk files.  Images are
     saved in xpic(L) compatible file format.  Its  main  feature
     however  is  its  ability to support multi-user editing ses-
     sions.

The system was implemented as a one-shot prototype rather than
generated using any sort of groupware oriented toolkit.  If you are at
all interested, I can send you more information including the full
manual page and a (LaTeX/PostScript) project report document.
