About ... 10 years ago I got a recruitment offer from a company working on remote collaboration tools for software developers. it was going to 'revolutionize' what was possible. but... i had to move to SF to work in their office. they didn't even see anything wrong or odd or off about the requirement.
This description makes me think of ScreenHero, which really was an incredible leap for remote collaboration until it was eventually bought by Slack — and the thing Slack eventually came out with for screen collaboration was weak by comparison. That was a real shame.
No, I never found something that was even close to that smooth, convenient, and efficient, and geared toward screen-collaboration first.
What everyone else offers is collaboration, as an extension of screen 'showing' (virtualized projection), which itself is packaged only as an extension of a teleconference.
