Five academics from around the world plan to open a new kind of online university early next year, built upon professor star power and students learning from one another through online social tools. The teachers will be volunteers, the courses will cost next to nothing, and no official credit will be given. The organizers call it P2P University (for peer-to-peer), and they hope to fill what they see as a gap in online-education efforts by traditional colleges, which often focus more on delivering full degree programs online than on one-off courses. The project is running on a shoestring, with the organizers paying the initial Web-hosting fees and volunteering their own time, though they may seek grant support in the future.
