I use the wine version of Hot Potatoes from http://hotpot.uvic.ca/
(not the java version)
karel the robot see http://www.cs.mtsu.edu/~untch/karel/
This programs run more robust and faster than in normal mode (running
on server) and I think they run as a local app. (I can not grep them by
""ps aux" in a localapp xterm . Only wine ! )
I also use a german ms-windows-based programm in school which needs
with multimedial-data about 500 MB on harddisk. I installed it only in
/home/wine (server) and not in every /home folder of every
autologged-in-user.
So I need the ability of ltsp-localapp to have access to /home instead
of access to / home/logged_in_user.
