Maybe the main document on the TV uses XHR to communicate with the TV channel server, but we should not care. > I dont see a distinction between messages and plain strings.

May I remind you that in broadcast situations, even a rather small library like jQuery can represent significant bandwidth, when placed in a carousel that needs to be repeated every few seconds. Most of the use cases may be expressed more simply within broadband scenarios, but broadcast-only scenarios are definitely relevant on a TV.
