I'm certainly not predicting that another CDM would be successful. Some have argued that DRM systems will die because of their violation of freedom and the fact that in any case they are breakable and hence have little utility. If these arguments are correct, content owners might be willing to support open source (and breakable) CDMs as a way of getting some degree of content protection without violation of freedom. Clearly that is not happening any time soon. > > Regards, > Rüdiger
