Hehe, yes. As told in the meetings I'm porting the current state/firewall.py. The first approach has been almost 1:1, only different (wrong) location and too large for a first iteration. So Gustavo, Roger and I discussed it and I create a new approach based on your and Rogers ideas and with smaller iterations. Roger had a nice idea how to handle all changes in a clean way in one loop with the help of individual goroutines. You already can see it for machines in the first propose. 

Rogers outline is here: http://paste.ubuntu.com/1087489/
