Hi, There have been various comments around recently about installing WN M/W with tar balls on the fly during jobs or possibly by the dteamsgm user effectively as experiment software. There is a draft here http://grid-deployment.web.cern.ch/grid-deployment/documentation/public/gis/Tar-Dist-Use_v2.2.0/pdf/Tar-Dist-Use_v2.2.0.pdf which I've been asked to give comments on so if any interested parties have comments let me know. This looks potentially to be a solution for a great many sites especially as we seek to assimilate non HEP farms. Steve -- Steve Traylen [log in to unmask] http://www.gridpp.ac.uk/
