NPCs that can hear without being targeted.

[JrFaust]

I've read through a few quests that could use this, an example is the prayer shawl quest.
Also I'd like to make a few custom events that would work nicer and be easier to write up, and maybe I could have some GM bots on my server.

But what might that do to the server?
Would that take up a lot of CPU time for NPCs to be "listening".


Thanks for your time.
