I work for Ericsson on content delivery solutions (of course from secure
origins). We do get feedback from some media houses and TV providers
(medium sized) that they would like to see mixed content approach for DASH
since the cost for DASH on HTTPS still is perceived as a painful cost for
them in the short term.

What is the latest status on Ryans proposal,
https://lists.w3.org/Archives/Public/public-webappsec/2015Feb/0371.html?

We would be interested in looking into this further (as a complement to
working on lowering the price point for dash-on-tls).

Best regards
Göran
