Very interesting plugin. I hope it will continue to develop and one day it will be production ready. Collaborative modeling and drawing with several people would be a fantastic tool!
However, I am afraid that some solutions regarding displaying elements in Model Views in Rhino will not be an obstacle to achieving full success.
For now, this is literally the first problem I thought of and tested. Unfortunately, the test did not pass.
The video shows that hiding an object by one user and moving the same object by another leads to desynchronization of the object’s position for users.
