Would Agile Licencing work for other "Technical" courses, or do you think that there is a good reason for holding onto the reigns to make sure certain quality is maintained? For instance, was thinking about certification - is it useful to be "certified" (!!), or is it better to have attended (or run) a course with materials that have evolved to be better each time the course is run?
