I have an idea that is sorta like the commands in ULX 3.0:
A posess command, like !posess <target>, which allows you to actually take control of them, seeing through their first person view and being able to control stuff like their props and things like that, while their controls are disabled while being posessed, so all they can do is watch from first person. Also, whatever the "posesser" does, it will appear as if the posessed is doing it. This would come in very handy, like if you were trying to show someone how to do something, you could just pop inside their body, show them how to do it, then pop right out, and they would know how to perform the action after viewing it in first person. Also, if someone is being stubborn, and does not do what an admin tells them to do, the admin could posess the person and do it for them. Obviously, this would be a very bad tool if used incorrectly, but a very useful tool nonetheless. I can imagine, however, this might be impossible or nearly impossible to do, but i just thought I'd let you know, because if it is possible, THAT WOULD BE SO COOL!
