I've never tried it either Jeebs, but I also think it would work well.
You might try using it like dip, and place a pinch in between your lower lip and gums. You could put the powder in an empty dip can, and no one would think twice about it (other than those who are grossed out by peeps dipping, of course).
If you try it, let me know. This sounds like a great way to fly!
