This occurred to me when thinking about AtionSong's volcano design, but it will be important for everyone if we ever build multiplayer Ages. (It's relevant for timed events even in Uru:CC Ages.)
Can you say "Everyone in this region panic-links *at a particular time*"? That is, on an event in a Python script?
Imagine a bunch of players standing in the volcano when it erupts. Or, say, people standing in a vault door when it slides shut. Or even a configurable maze, and the controlling player builds a wall where you're standing. The easiest way to maintain game consistency in these cases is to panic-link everyone in the affected volume.
