The hook is executed after the caches, currently. I do not feel the current hook implementation is suitable for RRL production; I do think it's a great playground for writing rate limiting scripts. The exact placement of hooks would be based on suggestions and requests from those writing the scripts.

Not sure - perhaps Mark can clarify.

I'm not aware of any scripts outside of that thread.
