New technology by Valve to counter DOS attacks

From this article:

"The latest build of CSGO has support for a new relay protocol, known as “Steam datagram relay”. Instead of communicating directly with the gameserver, your client will select a relay and communicate through that relay. There are a few advantages of this method. First, this will eventually allow us to remove gameservers from the Internet completely, which greatly protects them against all sorts of attacks. Second, if a DoS attack prevents you from communicating with a particular relay, the client will automatically switch to different one within a few seconds. And finally, having different relays to choose from means the system can select the route which actually results in the best connection to the gameserver. For example, this relay protocol has been in use on Dota for about a year now, and the majority of Dota players playing in the US are experiencing a modest ping improvement compared to the route direct to the gameserver that they would have gotten with standard IP routing, because their client is selecting a relay closer to them. This also means that their traffic spends more time on Valve private dedicated links compared to the general Internet."

I wonder if they'll commercialise it?
