As of 2005, UMich's mfile service (based on filedrawers) doesn't use WebDAV, but instead offers a web-application based interface to interact with AFS. We've written a utility called waklog (web aklog) which acquires the user's credentials, and allows us to manage that user's filespace. The filedrawers UI demo can be found at http://filedrawers.org/filedrawers_demo.php. More information about the project can be found at http://www.filedrawers.org/
