iTunes on Campus
Napster has recently seen some sucess in providing volume licensing to several colleges. Napster's unlimited subscription service allows them to accomplish this -- limiting access to music for the duration of the subscription.
iTunes on Campus does not provide a similar service and appears to be more of a marketing effort with permission for institutions to distribute the iTunes software:
This license agreement will allow you to distribute iTunes as a download from within your campus network or through individual CDs that you create. As a part of this program, Apple will also provide to you the creative artwork (for newspaper ads and flyers) about iTunes that you can use to tell students about iTunes.
