re: WebGL games. The clients will all be "open source" (as they're javascript). What effect do you all think that'll have on the future web-based gaming industry?
Since I'm currently developing a WebGL game I'm actively searching for ideas to detect that behavior.
The only solution I can think of is, to capture any data with timestamp coming from the client and applying some tests to it like "is the client sending more messages than a normal client" or more advanced: sending the input through a statistical filter to detect possible cheating and investigate from there on.
It might be an idea to think about the actual mechanics of the game once you've come up with a possible solution so that the game itself doesn't invite cheating behaviour or at least makes it easier to detect. i.e. Making it physically impossible to shoot faster than a specified rate or move too quickly/accurately, etc.
Good luck!
