Since each view has beed capsulated in content wrapper, direct access from view to view is not allowed and we'll need to propose a mechanism(maybe using broadcast channel api) to communicate across different views.

I still don't think this is something we want to do; instead we want to change a model in the Worker, then from the worker we would ask to change all views (through the use of events). Basically using this simple MVC flow: User action -> Controller -> Change model -> Change views ^ | | | -----------------------------------------------

Looks like our inter view communication will be based on service and bridge anyway, so duping to bug 1162031.
