It's certainly true that a fully custom solution costs more money than is available. However, there are only a finite number of custom solutions out there. Once you've built a solution for one Tai Chi instructor, a very similar solution will work for most other Tai Chi instructors, as well as Karate instructors and piano instructors and the guy who will teach you how to arrange flowers. I think that a large enough organization (even a loose collective of individuals sharing best practices) could reduce per-customer overhead sufficiently to allow this to work at scale. With a collective memory of thousands of 'unique' (but only to a point) situations, it'd be far less costly to offer custom service.
