Example 2: SASSE shared text editor.
This editor uses scrollbars to provide awareness of the other participant's
location in the document. What about a SASSE for 3,4,5,,,,n users (e.g.
for a large technical document). Scrollbars would cover half of his screen.
Example 3. Possibly workflow systems

or if there is more than a critical mass (e.g. E-mail). Filtering is NOT
a satisfying solution for E-mail.
