Just as a point of interest, at the end of the channel menu on my Freeview box channel 704 is listed as 4T interactive. The BB press release last week was very ambiguous regarding interactive on Freeview, it seems as though there is a ready made spot for it already. The BBCi programmes are shown on the 700 channels. Having said that E4 is listed for channel 14, E4+1 cannot use channel 15 as it's already occupied by ABC so maybe 704 will be for E4+1?
