Awesome stuff. I made a nifty trick with the speed thing by putting an RF pickup on one side of a line of belts and a One Way (with the suggested addition in JCS.ini) moving it four tiles back. With a bit of covering by layer 3, this makes it appear as a moving line of manufactured ammo, even though it's still the same event moving along the line and then jumping back to the start.

Thanks for your time you spent on writing all this. I'm going to read the Remembering Triggers article now.
