I'd like to offer authors the possiblity to allow access to videotutor content without requiring login. In principle, guest login allows that, but many potential viewers leave the login page without trying guest login, which is a moodle-only concept.
Messing a little bit around the line:
require_login($course, true, $cm);
in view.php and other pages, and adding an option in the configuration, it should be easy.
