I was searching through google patents and I found this:
http://www.google.com/patents?id=AMN-AAAAE...log+game+server
I also noticed the Effective Date on it:
Issue date: Jan 30, 2007
I think its kind of funny that some guy beat Valve, Even Balance, and all the other AC companies to the punch. I wonder what will come out of this once the patent becomes effective tomarrow.
