Yawcam

Hi, I install yawcam in a notebook and I need to install in another one, but both are in the same network, whats the difference about the multiple instances metod? For install in 2 notebook only need to change the port of yawcam?

Ex: note1 ip 222.222.222.222:8081
note2 ip 222.222.222.222:8082 ???
