There is a lot of misinformation going on in this thread right now, and I don't really understand the agenda behind it. If UDP traversal is superior to UPnP, Valve will move to it, and then Ashes will support it. If you are on a crusade about it, start complaining to Valve, not Stardock. Nearly everyone is operating just fine with Steam's current method (or Steam would have died long ago), so it's going to be an uphill battle. Good luck.
