The only problem i had was grabing the page ; the website doesn't allow without a valid user-agent. So i just copied myne , using tamper data in firefox and the switch -A in Curl.
I then wrote a simply C program that levarages this feature.
Bear in mind that this is more like a POC; if you really want to track your mates / games they are playing, there are dedicated sites that can do that (e.g gametracker, and so on).
The program is here.
