I am very reluctant to develop and deploy a software probe similar to SETI@HOME or various browser plugins. There are many reasons for this and they are explained in the article. The real show stoppers for me are the responsibility that comes with running a networked application on a user machine and the difficulty to produce verifyable and above all "comparable" results. The RIPE NCC cannot run the risk to inadvertently provide a "RIPE BotNet" or to do harm to a users system. Neither can we use measurement data that is taken and processed in environments over which we have little control. Could we trust that data?
