Lapham's Quarterly and the Institute for the Future of the Book are hosting an (ongoing) collaboratively annotated version of the Iraq Study Group Report online. The just-launched project only has a handful of annotations at this point, but the design and process of the Website seem very well done for this sort of work. The first round of annotations are being provided by a long list of (mostly leftist/liberal) social critics (Barbara Ehrenreich, Daniel Ellsburg, Stanley Fish, Ralph Nader, etc.), but a second round in January will open the process to everyone.
