The MIT Center for Collective Intelligence is publishing a collaborative book called We Are Smarter Than Me. From the site:

Be an author of the first networked book on business. Together we will write the book on how the emergence of community and social networks will change the future rules of business. Collaborate with authors from MIT, Wharton, and thousands of professionals from around the world. See your name in print when the book is published next fall by Pearson Publishing. Meet your co-authors in March, 2007 in Las Vegas at the Community 2.0 event.

I wish I was teaching a computers and writing class next semester. This would be a great (semester long?) project.
