Yes, we can track in-game achievement feeds. Aren't the ribbons time based on how often you can get them in a day? I honestly don't pay attention to the ribbons so I don't know which ones are available or the rules behind them.

The zone ID is just the continent the player is on which is one of three values. I'm not sure how you can manage to kill someone on a different continent... I believe mines de-spawn when you switch continents. If we were given actual region IDs or somehow able to track the distance in meters we absolutely would want achievements for that. That currently is not possible.
