I doubt it - ITVX isn't even now available on all but the newest Freeview Play devices and none of the commercial PSBs have shown any interest in making their on demand content available via the Freeview EPG or red button in the way the BBC and some other commercial broadcasters have (indeed 4Music had the extra channels for a decade or so but have now scrapped them, and C4 never used the technology for anything else - i.e. the Paralympics)
