technosaurus Registered Member Posts 2 Karma 0	Multiple desktop sharing? Sat Oct 18, 2008 4:59 am Is it possible to set up your multiple desktops to share 1 desktop to one user and another desktop to another user up to say 32+ desktops and 32+ users? (such that one user/invitee only has access to their desktop and the admin/inviter has access to all 32 desktops as normal) This would provide 1. Quick and dirty method for setting up thin clients that would be much leaner on server resources. 2. Administrative monitoring capabilities similar to iTALC - with fewer resource requirements. (beneficial in classroom environments) 3. Real time group collaboration on resource demanding projects such as video editing. 4. Many more ancillary benefits.

Sun Oct 19, 2008 5:08 am If you were going to use it as a thin client, then you could just limit a user to one concurrent logon at a time. Alternatively, you could customize the global logon script to logout a user if they are not allowed to logon at that terminal, but it would be a pain to manage.

Fri Oct 24, 2008 8:19 pm I guess I need to describe what iTALC is What is iTALC? iTALC is a use- and powerful didactical tool for teachers. It lets you view and control other computers in your network in several ways. It supports Linux and Windows 2000/XP (Vista support will come) and it even can be used transparently in mixed environments! In contrast to widely used commercial equivalent software, iTALC is free! This means you do not have to pay for expensive licenses or things like that. Furthermore the source-code is freely available and you're free in changing the software to fit your needs as long as you respect the terms of iTALC's license (GPL). Freedom in two ways! Features iTALC has been designed for usage in school. Therefore it offers a lot of possibilities to teachers, such as see what's going on in computer-labs by using overview mode and make snapshots remote-control computers to support and help other people show a demo (either in fullscreen or in a window) - the teacher's screen is shown on all student's computers in realtime lock workstations for moving undivided attention to teacher send text-messages to students powering on/off and rebooting computers per remote remote logon and logoff and remote execution of arbitrary commands/scripts home-schooling - iTALC's network-technology is not restricted to a subnet and therefore students at home can join lessons via VPN-connections just by installing iTALC client Furthermore iTALC is optimized for usage on multi-core systems (by making heavy use of threads). No matter how many cores you have, iTALC can make use of all of them. This really does nothing more than the KDE with desktop sharing except that it can be multiple different users (and requires a lot more CPU and RAM resources) Implementing "multiple desktop sharing" in a similar fashion could accomplish the same thing in a much more efficient manner. If anyone is familiar with this particular source code in KDE - please advise on the level of difficulty.

Fri Oct 24, 2008 9:04 pm No expert, but my hunch is that opening 32 concurrent desktop sessions via vnc would take some huge resources.... Still it remains an interesting thought. You might have a look at web based options like vyew or yuuguu, but I have no idea if you can setup multiple sessions via any of them. I recall something called CoolCollaborator. It is a java based app that allows multiple users to share screens at the same time. The underlying protocol is vnc by the way. XiniX, proud to be a member of KDE forums since 2008-Oct.

Fri Oct 24, 2008 10:45 pm You cannot however control access to Multiple desktops. it is not designed for that and is designed to streamline a single users workflow. i would strongly discourage that because each user would have access to the all files.
