Ciril- I am also forwarding this reply to LTSP list in case some one there spots a goof or improvement.
I understand your layout to look about like this: Video ---------\ Mail -------------\ /---LTSP-\ /-- Confernce---------------LTSP---------to Clients Management-/ \----LTSP-/ \-- To start I am assuming you are familiar with basic Linux/unix desktop usage. An LTSP client will function _exactly_ like a normal user desktop as far as email, web, writing programming, and storage to home dir. This transates to anything you can do on teh Thick Server( here to LTSP server) you will be able to do on the clients with a few exceptions. The execptions are all related to hardware such as sound, webcams, removeable media, locally attached printers. So the real issue you are going to have will be in the video conferencing area. You will to setup the ltsp sound servers for the audio, and do some performance testing on the video feeds to see if you will need to run the video clients as local apps. Video will use alot of CPU and bandwidth. I think the gigabit switches will give enough bandwidth. Management server may be come an issue because LTSP does not at the moment have a good default way to centrally manage several LTSP servers. A solution would be to have the root directory and boot kernel served off of the management server either directly or by nfs mounting them to the LTSP servers. This would allow you to make the changes on one box and have it show up everywhere. You would still have the clients running the remote X sessions on the current LTSP servers.
