Unless someone finds the coding in a few games and can determine that it is located in the same spot on every game, so that a patcher can be created, Its going to be alot of work to do on every game. Ping is measured and the only way it can be fixed or lowered is to get a faster up speed, better ISP, or be able to bypass ISP barriers and filters that restrict your bandwidth, which are pretty much the same thing.
The ping limit can easily be avoided if we had more users. Problem is, we don't! People are still too busy trying to unban, uncripple and whining about the same to realize we are trying to get some games going. Games they can easily be playing if the got on Xlink.
