Ok so i was wondering

I was wondering if anyone has a program that theres a server pc then a client pc.

The server pc controls a user list of users that can login on the client pc.

Then the client pc when u login it opens a door on the left or right side.

Does anyone have something like this?

Someone's gotta. But you might be better off just searching for it, most of the ones I'm familiar with deal with file serving/receiving or relaying rednet traffic rather than opening doors.
