NPCs that can hear without being targeted.

[JrFaust]

My main goal was to have a situation(s) that you might be interacting with an NPC and maybe a PC while the guards "listen" for key words. Then high jinks, warnings, and arrests would ensue. And I guess one might be able to use it as an automated GM for small tasks, but I see that getting used and abused.

But there are ways I think of simulating "listening" I just hope that they way I want to do that won't tax the server just as hard.
