Let's not forget the work Ziggo is doing in the Netherlands. Back in November last year, Broadband TV News reported "Ziggo has been testing the CI+ 1.3 version of its Cloud TV interactivity for the past few months... Starting Wednesday, November 6, STB-less viewers can also access the additional features. It is a worldwide first to offer interactive TV over a common interface."
