As More Universities offer LBS Apps, Will Towns, too? What about standards?

The Duke Chronicle details what some call iDuke, a mobile app that offer the university calendar, maps, real time tracking of busses and the like. It’s expected to be available around spring break. It’s parallel to an effort at Standard dubbed iStanford.

Now, this is all well and good, but - does it mean that those who travel among campuses will be downloading new, different apps all the time? If my town offers up iSomerville (not sure that’ll happen any time soon…) will I also have to load up iCambridge to be sure I get bus tracking when I visit my Dad in the town next door? Are there standards and are folks interested enough to have a single client that could tap into data delivered by standard interfaces from providers representing different geographies?
