i could do it in around 3 hours, i actually have one witha server and stuff ill attatch it below, all you gotta do is run the server, then each client connects, you'll have to work out the servers ip address

i didnt finish it 100% but its in a working state there may be a few bugs though

the ip at the moment is set to loop back to your self so you can run server and client on same machine (the coding may be bad it was done a year or so back)
