My understanding is that one can enter a URL for a public website/page. It is, however, untested, and untestable. The "shell" interface is not there to make this useful yet because there is nowhere currently that any user can view a list of departments. Initially, Sloan and OF discussed creating an outer shell for non-.LRN users for viewing public, rather than private or confidential data, such as these department URLs, course syllabi, group descriptions (maybe), etc., but it is not yet implemented.
