Currently Awesomenauts uses the Steam p2p library for networking. This works well in general but there are some negative aspects to it. There is limited control: We can't choose which ports to use, or customize QOS settings. Steam also adds 20 bytes (on top of udp and ip) to each packet that is sent. We've done many bandwidth optimizations and getting rid of these 20 bytes is getting more and more significant. These are the reasons we are looking for an other network library. And I'd like to get some advice on this topic 
.
.The Steam networking API is build on top of libjingje so we could just use that.
It supports NAT punching just like the Steam API.
We can choose which ports to use, which is good for players with routers that don't have UPNP.
We'll lose the 20 bytes steam overhead per packet.
We can access the QOS (DSCP) setting.
This seems to be a good choice. But is it? I'd like to hear about other developers experiences with libjingle in games, and also with other networking libraries.
