Well, that would be something that Ettercap would be handy for. The wargames tutorials I wrote might also be some good guidelines. What you might want to do is not tell each other what is going on the boxes and set a start date to investigate the "new machines". Don't give out IPs and figure out what each device is in your network via utilities like nmap, SARA, Retina, etc.
