True - if you share your window or display on CoScreen, you can decide if you also want to share remote control or not. It’s a global toggle for all the windows you share. Also, only users who have the invite to your CoScreen (and therefore have a secure token to get into it) and are with you in it at that moment, would be able to type into your window if you allowed that.
oh dang, ok... the "Home" link on your blog should really go to that page instead. I clicked home assuming it would take me to the landing page, then didn't even check the url (which was https://www.coscreen.co/blog/tag/deep-collaboration/ for some reason? why is that Home?)
We have not tried Unity ourselves but would be eager learn more about the use case. We've heard from a few users who use it to play games together.
Because the sharing approach is video-based, it can stream any kind of content, no matter if text or moving images. That being said, it takes some resources to shovel 4k images with a lot of changes from A to B so it needs some free capacity to run smoothly.
