Thought I'd post my results along with some thoughts.

The better this starts to work, the more likely I'd suggest that blizz finds a way to limit this functionality. Just a conjecture.

That said, I like it a lot and hope you or others figure out a way to improve this so that it works a bit better and less buggy. I ended up getting stuck with my camera oriented 180 degrees in the wrong direction and had to relog to fix the issue. Some sort of /pnklook configure command would be good that set the camera to some sort of "safe" default position prior to executing the algorithm might be helpful.

Secondly, there still is the issue of a good keybind option. I searched around and found a few things about binding mouse-clicks to keys but didn't follow through to really try it. Maybe tonight. all in all, cool work and keep it up.
