… makes for an interesting / scary read. 

I know that W3C has been engaging with various parts of the TV/broadcast community, but it seems like there's been a failure of some sort here, at least based on this; violating the origin model is pretty serious. 

Has there been any interaction between W3C and stakeholders there about this? It seems like we should have a liaison of some sort with DVB would help. It's also a timely reminder that as we get access to the Web in "things" — whether they be TVs, cars, refrigerators or whatever else, security (amongst many other properties of the Web) needs to be carefully guarded.

Cheers,
