Last weekend at Annahoeve in Achtmaal the Dutch Refugee Council of Midden Gelderland announced that they succesfully completed a pilot where they migrated 100 machines and 200 users using NX technology and the KDE desktop. Jasper van der Marel held a presentation during the Dutch KDE-PIM meeting where he explained how the current setup was done.
The goal was reduce costs and to be less dependant on closed source software. At first the Dutch Refugee Council opted for a LTSP solution but because this was missing important compression features they choose the NX technology from NoMachine. Some of the applications used are OpenOffice.org, Kontact and Kiosktool.
The project started in 2003 when they did some tests on their local network and in the first half 2004 they tested connections between Arnhem and Amsterdam, two cities 100km's apart. At a certain point the sysadmins of the Dutch Refugee Council of Midden Gelderland had to decide on a desktop. The decision fell in favour of KDE chiefly because of the availability of the Kiosk framework.
Because of this successful migration at the Dutch Refugee Council of Midden Gelderland other regions are now also planning a similar migration for their desktops. You can read more about this migration on Open Source Nieuws Nederland (Dutch). A quick translation into English can be found at the Dutch KDE website thanks to Rinse de Vries.
