[Mod Request] Rangefinder and setpoint

[cactuz_pl]

I have two ideas:
1. Is it possible to create a mod that displays the distance from other players?
2. Is it possible to create a mod with that you can mark the places and displays distance from this places? These points are only visible to the player who created them. (to prevent spam)
For example using commands:

/setpoint [point_name]
/removepoint [point_name]

My vision:

This would require C++ of course; I'm pretty sure it is possible. It would be great, yes. :D
