Connection Between Forms On Different Computers?

[Conejo]

Im working on a desktop sharing application, i already know how to capture screen frames and display on picturebox, also im learning how to use winsocket, but is it possible to make a connection lets say you type the persons ip which you want to conect to, then they must have the app installed first and they get a prompt saying that there is a connectioon request and desktops are shared. please give me a detailed explanation of how to do this through winsowck.
