I know this isn't exactly what you asked for, but CNN (or someone) syndicates their closed caption feed over IRC in #cnn-live on EFnet. This came in super handy during 9/11 when every major news website was down and I was at work with no radio or TV. posted by nitsuj at 4:08 PM on September 22, 2008
Not sure I understand the question, but if I go to CNN.com right now there's a link to view live coverage. I just opened it up and it looks like this anchor and content are both cnn.com-only--this isn't a stream of the real deal, so to speak.
Of course, they do put the real-deal online for big, pre-planned news events. I watched election returns during the primaries, as well as the primary debates and both of the conventions on cnn.com and/or msnbc.com. These all included coverage of the events themselves and commentary by anchors/pundits before and after the main event.
(Oh, and during the days leading up to Obama's VP selection CNN had a super-creepy "Veepwatch" live feed from outside Bayh's and Biden's homes. All day long.) posted by rafter at 5:42 PM on September 22, 2008
