@ Gormand: didn't ghost running get disabled a couple years ago??

I used to do this all the time to get to a new zone, but with one of the 2.x patches I ran a lvl 1 night elf from the starting zone to the GY outside Ironforge, clicked the spirit healer and rezzed right up immediately.

... Immediately, right back back in newbie zone, after wasting about 20 minutes of my life running across the globe in spirit form. I haven't tried this trick since, so maybe it's has been changed since this happened to me.
