I read that same quote elsewhere and its really surprising to me. As far as I'm aware Muni is super stingy with all of their data. Even their route data isn't freely available for reuse. For instance, I'm trying to put all the Muni lines into openstreetmaps.org but I can't just go on to Muni's website and copy the data from their. If you want to use that data you have to enter into a licensing agreement with Muni where you have to do things like give them quarterly reports on how many users access that data. I've been manually going around and regathering it myself just to avoid having to deal with them.
According to some Google people I spoke with at WhereCamp a bit back even they had to sign that agreement in order to put the Muni info into Google maps. I find it hard to believe that with those kinds of policies in place Muni is going to let people freely view their realtime info, especially if it might make them look bad by showing exactly how often they're late.
However, if I'm wrong and there is someplace where Muni makes this data available I'd love to here it. Otherwise I'm just going to assume the Muni spokesperson is fibbing and hopeing the whole situation blows over quickly.
