In my Unix days, I used a support tool called Double Vision that allowed someone to take over another tty session. This was immensely useful, so that you could debug their actual session, not just try and create the problem from scratch. Our application is character based, and the users have telnet or ssh sessions going that launch the software. I am guessing that this product did something like a Tee command to repeat all the same screen I/O to multiple tty devices. I know the company who makes this product is still around, and has a Linux version. But I was curious is something like this already existed as a open source equivalent.
