Okay, I'm 100% sure it is not nostril glow.  I'm calling it nostril specular fubar.

It seems to be happening due to a combonation of 3 things: the image map (I'm thinking it's the tone and color of the skin), the amount of specular reflection, and the angle of the light.  Whenever I disable the specular component, the problem goes away.

I'm thinking the best option for this problem would be a blender map which turns off specular for that area when it pops up.

WARK!
