If you want to do this now, you can, using things like vncserver on the application server and have your thin clients connect to VNC sessions that run fullscreen on the thin client. This work has already been done in multiple ways. You can take a look at www.pcxperience.org for two such ways (vnc-quick and vcx-X-session -- available on the LTSP Enhancements page). Also, someone else added support to the -init mode for Xvnc that allows you to connect and reconnect to already running sessions, which is a much nicer way than possibly the other ways. Haven't checked into it yet, though.
