Stanford Magazine, the publication of the Stanford Alumni Association, provides a nice piece in its November/December 2008 issue on the Preserving Virtual Worlds project.  Under the title "Saving Worlds: Preserving the Digital and Virtual," neatly summarizes the project and its work, with quotations from Henry Lowood (me) and Beth Dulabahn of the Library of Congress, as well as a couple of nice photos.  By the way, the workshop described in the article was "Preserving Knowledge in Virtual Worlds," put on as part of Media-X' Summer Institute at Wallenberg hall.
