An old captain/fo utility.. is it still around?

u know, there is a captain/FO program out there, where u can connect with someone in a multiplayer game and one person does the actualy flying and one person, as the FO, does the flaps and gear and stuff, and u both see it from the panel perspective, so you are in the same plane connected through an ip, just like you are in the same cockpit. I havn't seen it for a long time and just thought about it, anyone know of where I can get it, or know of what im talking about?
