I guess as others have tried, I replaced my nektulos.* files with what is currently in the Live client, and zoned in. Total blackness, and it "sounded" like every NPC in the game was right on top of me. It was too scarey, I had to zone out!
So I guess Nek v3.0 won't work for now :( plus, you can't really patch that out to your players anyway, I suppose.
