We showed how users could be added to sessions by clients joining a session initiated by the master.
|
Alternatively, one can use a remote open command shown on previous and next two pages
-
This is appropriate when one is sure that a group of users need to participate. This is typically the case in a distance education class when students have logged into Tango and teacher wishes to launch a shared application (e.g. the cross-product applet) on all student machines.
|
When teacher highlights the cross-product session (and no other users have joined), he or she is offered the allowed choices:
-
local close which will terminate session or
-
remote open which can spread session to any of the other users
|
|
The dialog box that jumps up allows one either to select specific users or all -- the latter is a good option for education when one typically wants all students involved.
|
|
We will see later how the configuration tab, allows clients to prevent unwanted remote opens cluttering their windows
