In the sense that a website operator must work with the CDM vendor to be able to authenticate the client CDMs and construct licenses for them. Whether this involves certificates and CAs specifically depends on the CDM design (it can also all be done with secret symmetric keys). Whether it involves some real-time b2b service or whether the website operator purchases or licenses technology to operate in house is also generally open. > > > The costs of deploying DRM on the content distributer side remain >> significant.

To use CDMs based on the existing DRM systems, AFAIK those are not free. So yes. > > > > > There are also pure technical reasons to think of EME as a waste of time, >> as in that it's already broken.

Please explain further. >From your site: *Important note* - By viewing the content of this website you agree to the following: - Copy is right - Free speech and privacy are not up for debate - Non Free software is evil For the record I do not agree to the third of these, nor to the first if it means what I think it means (all copying is morally justified). These are huge and far-reaching propositions. You clearly believe it is reasonably to place these as conditions of access to your content. Why is it not reasonable for a content owner to require the use of DRM ? ...Mark > > > > -- > Emmanuel Revah > http://manurevah.com > >
