The "problem" of the X technology used in LTSP is that it is a shared-state model. The state of the screen, among other device dependant stuff, is on the terminal, while the state of the applications is on the server. This has enormous advantages when it comes to complexity and ressource: There is no need for the server to run a framebuffer copy of every client desktop. On the other hand, rebooting a client means losing the session. Hibernating it is probably not better: The processes on the server need to be aware of the fact that their screen is currently sleeping, which they probably will not work with at all. A solution for roaming users with persistent sessions (quite like the Sun solution, if you happen to know it) is to run a X-proxy on the server, and on every client connect to check wether there already is a session for that user - in case yes, connect to the X-proxy where that session lives, else create a new session in the X-proxy and connect there. afaik, some Gnome people started playing on that. In doubt it means a higher load on the server, but that might be marginal if users understand that playing a video and then leaving the session is not acceptable... :-) I don't know of any deployment-ready solution right now, sorry.
