I mean you cannot prevent someone from downloading the material that you have as a streaming solution and putting it onto whatever channel in the end the question is is the policy an adequate means of either promoting open video or is it not even though I'm quite skeptical with regard to policies, I would like to advocate to work on such a policy, but I would like to propose working on a shared policy here and the idea of course is that we have a number of rather influential institutions here at the IARU conference and also I think that the Opencast Community is a good vehicle to work on such a declaration on open video.
