I like the laser pointer idea.

One thing I find VERY annoying is when I am using my F80, is that stupid low-light assist light. Some person at Nikon decided to make it an insanely bright white-light.

Which totally screws up shots when you don't want people to notice. They all turn to see what the light is!

I like the assist light on my flash which is RED and very unobtrusive.

Red is the way to go. I am thinking of coating the assist light red on the camera so that when I am shooting fast film I can focus easily and unnoticed.
