I'm not sure if you're thinking that thought through. Yes the higher education institutions could sell the personal relationship with the expert. But they don't necessarily have to do it in a classroom environment. Video chat is main stream now, and it can even be done as a classroom. Brick and Mortar schools could easily become a thing of the past with the advent of Broadband availability to most/all homes (even internationally).
Essentially, Colleges and Universities will still exist, but on a much smaller footprint, and will become Media creativity hubs (Compute/Storage farm, and pure research facility), where professors will generate content for online consumption. Then once their curriculum for the semester is complete the head home (wherever that may be), and make themselves available for Video/Audio conference, and/or if they choose a live video classroom.
Universities will become a true sense of what everyone thinks of them now, A place that will give you a piece of paper after several years of paying them 10s or 100s of thousands of dollars. Then you use that paper to get you in the door of you first job and not much beyond that...
