An educational software organization in Germany is pilot testing an educational software system based on virtualized Debian/KDE desktops More here

The Desque technology aims to let schools with older PCs or inexpensive thin clients access modern Debian/KDE desktops running at a remote, centralized location. The desktops in the pilot program are hosted in Hamburg, Germany, on quad-core Xeon-based servers partitioned into multiple virtual machines using the open-source XEN hypervisor paravirtualization technology. The desktops can be accessed by students with “standard” broadband connections, according to NoMachine. Along with the obvious advantages of virtual thin clients — centralized maintenance, low-cost clients, and energy savings — students and teachers are able to access their desktops whether at home or at school, NoMachine suggests. Since all processing happens on the remote server, remote client PC requirements are reportedly modest.
