It is possible to play 0ad from serverA using VirtualGL (http://www.virtualgl.org/). Install TurboJPEG and VirtualGL from sourceforge on the serverA and computerB From the manual: TIn the same terminal/xterm window of the Thin Client, open a session into the VirtualGL server: /opt/VirtualGL/bin/vglconnect {user}@{server}Replace {user} with your user account name on the VirtualGL server and {server} with the hostname or IP address of that server. In the SSh session, start a 3D application using VirtualGL: /opt/VirtualGL/bin/vglrun [vglrun options] {application_executable_or_script} {arguments}(I have problems with the sound, but that is another issue) Enjoy it!
