Oh I remember this... I think I still have the beta stand alone app installed somewhere...
I used to try it every now and then... The streaming sucked. I don't know what bandwidth it required (the image quality didn't look like it would need much), but it was completely incapable of working out how much it should buffer in advance to provide smooth playback.
Result, 10 seconds of video, 20 seconds of waiting... 10 seconds of video...
I would say "repeat until end of video", but nobody puts up with that for a whole video.
Come to think of it, I don't think I even watched a whole video when it did actually stream (wind blowing in right direction etc), cos there wasn't anything worth watching!
Without content it's going to be pointless... And given that BBC, ITV, Channel4 etc all have their own view on demand system (which do stream quite nicely), I don't think they'll be able to get it.
