So while I am all for this if you do it right, and it certainly removes the risk of spraying mist everywhere, it's also hard to see you didn't put the air where you wanted it.

It's true. It's also worth pointing out that with those nozzles you still need to cool the bit with a proper speed and feed setting for getting chips of a proper size. I can't speak from personal experience but the software package that comes up over and over for calculating speeds/feeds is this one (G-Wizard): http://www.cnccookbook.com/

Would definitely include that in your CAM software stack.
