Yes you can share UI from webodm with users. but you should definitely run ODM securely before opening it up to the internet. also setup through a DNS service redirect service like NOIP or something similiar.
After all that you would need to setup users and permissions for those users.
You could set them up with the Dockerized WebODM install, or possibly the WebODM Lightning Manager for Windows, and then provide them with the all.zip exports so they can import them to visualize and make measurements with.
You can also share your instance over the internet, but that opens a whole can of security worms that I don’t believe is worth it for most individuals.
