iTunes U has arrived, giving higher education institutions an ingenious
way to get audio and video content out to their students. Presentations,
performances, lectures, demonstrations, debates, tours, archival footage
— school is about to become even more inspiring.
Designed to be completely intuitive, iTunes U is based on the iTunes
Store.

Good broad resource of people active in producing and using podcasts in education.
