Well, registration ended yesterday (argh) but the Peer2Peer University will be worth watching:
The courses do not have a traditional professor at the front of the virtual classroom. Instead, a facilitator (who volunteers his or her time) manages online discussions, but students are expected to essentially teach one another (and themselves). Sessions last only six weeks, to help nontraditional students fit the courses into their schedules. No credit will be granted by P2P University.
