One of my biggest gripes about LTSP is the lack of thin client session protection. If you use the NX thin client system (
http://www.nomachine.com/ or
http://freenx.berlios.de/) and your thin client crashes, gets disconnected, or looses power, when you log back in your session is still as you left it, just waiting for you to continue your work (all your programs that were running before the crash, are still running).
If you are using Ubuntu LTSP, however, and your thin client crashes (this is not extremely unusual, albeit very annoying), the session is completely destroyed and all of the programs are shut down. A session saving feature is extremely important, especially during this time in development when not all the LTSP bugs have been completely ironed out yet. Eventually I would also like to see thin client sessions blessed with the ability to log out of the currently used thin client, without shutting down the running programs.
I recognize that this feature will probably steal more server system resources (all users could possibly have running sessions on the server, even though they are not currently logged on), and should therefore be optional, the option should, however, defiantly be available.
