Apple - Education - iTunes U

Jeanne just emailed the faculty tech liaisons about this, and I'm posting it here, because I'll lose it in my email:

Apple - Education - iTunes U:

"iTunes U* is a free, hosted service for colleges and universities that provides easy access to your educational content, including lectures and interviews 24 hours a day, 7 days a week."

Seems to good to be true... where's the catch? Here's some more text from the site:

"Instructors can easily post and change content on their own without impacting the IT department and allow students to upload their own content to share with professors or with the class. All content is stored in an Apple-hosted repository that can be browsed and searched, and configured to provide open or secure access as needed."
