I think EME shouldn't pretend to involve CDMs for use cases like this. AFAICT,
the proponents of EME don't intend to deploy EME solely for transport-level
security. Transport-level security is already addressed by https. If there
truly was demand for masking content on CDNs from CDN operators, we should
address that case with Hixie's http+aes—not with EME.

I object to EME suggesting that it addresses use cases of this kind.

The real use cases for EME seem to involve only this sort of CDMs.
