One of the projects I've been very involved in at OSAF has been the Cosmo project, an effort to take existing open-source WebDAV server technology and turn it into an easy-to-install, easy-to-administer "sharing server" for use by Chandler -- but also supporting standards that make it easy for any client to share too. Last week, Mitch did a demo with Cosmo in the background for the first time and it went smoothly. Thanks BCM!
