Going to class on Second Life?

As I was browsing through TechCrunch, I found an article explaining how a Sussex University, in England, is now fully on Second Life.  There is a link to the official Sussex University’s website outlining how they intend to utilize their presence on Second Life.   Although the school is developing exactly what students may do while on Second Life Sussex, it seems as though online lectures and seminars for students is going to be one of the main uses.  It also explains they want to use it as an outlet for students to show off their talent in the arts.  It sounds fun, but I wonder if it will catch on with students?  I think I would rather attend a seminar in person.  But maybe that is just me.
