I think there are some advantages to getting the scripting into a
seperate process, which lets the OS ensure that scripting doesn't thrash
out the rest of the engine.

Out of curiousity, what is the current reason that scipts don't work
with multiple regions (even when the scripts are stationary).  Perhaps
starting to explore that issue will lead to some ideas on this front.

There is no silver bullet.  Plus, werewolves make better neighbors
than zombies, and they tend to keep the vampire population down.
