This is an interesting idea. I wonder how you will grow it? Most University IT departments are understaffed and overworked. Even though they should provide these services, they often can't. Are you planning to charge universities for providing this service?

It seems to me as if academia.edu has plans to provide library services. Personally, I don't like the commercialization of libraries, especially when library scientists are coming up with excellent solutions (like http://xxx.lanl.gov/ .)

Either way, there are many directions academia.edu can go, must be an exciting time for you. Good luck.
