That would be really cool, but also really expensive - gyms have thousands (tens of thousands for some) of holds and they're usually cleaned by power washing and otherwise constantly abused. Maybe a middle ground would be computer vision? Not nearly as accurate or comprehensive of course, but a lot less hardware. (Most gyms in my experience have comprehensive camera coverage already for insurance purposes so I don't think there would be any additional privacy concerns).

Make a Spline Web App with the routes drawn on the spline doo-dad:

Can see a simple route design widget in spline that can be a nifty ux for a climbing thing that uses the app ID.

Can you clone an Instant AppID?

I know I am just thinking out loud - but its pretty easy to envision how to use these neato tools and services that have been cropping up recently... Its inspiring.
