The Chronicle of Higher Education is reporting that Apple Computer is releasing iTunes U (http://www.apple.com/education/solutions/itunes_u/), a service that allows colleges and universities to record, upload, and store course lectures in Apple's popular iTunes Music Store.  The Chronicle article is available to non-subscribers and reports that colleges can customize their iTunes U site with school colors and logos.  Stored lectures can be made public or restricted to certain groups.  Access to lectures can be controlled using existing college user ID's and passwords.
