Why doesn't Disney publish live wait times like Universal Studios?

Universal Studios provides real-time updated wait times for all their rides via the web at http://66.77.171.132/MobileWeb/. This allows guests to use their cell phones with web access to check wait times while in the park. In addition, it would allow some nifty data collection/prediction of crowd levels for all those ultra-planners out there. I can't think this would be all that difficult to pull off from a technical standpoint since Pal Mickey seems to know this information. So either they haven't thought of it, they don't see the value in it, or they don't want to give that data away. Seems like a cheap way to vastly improve customer service to me, much easier than the the Nintento DS solution they have been reportedly testing, anyway.
