One more thing, couldn't you use GPS to figure wind direction and speed by doing a contant rate full circle and looking at ground speed variation at different headings? Might take some software to make it easy, but why wouldnt it work?
I use a GPS when flying powered parachutes, and yes, what you are describing will work. Watch ground speed and do a 360, min. speed is directly into the wind and the difference between min. and max. speed/2 is the true wind speed. I might be a bit concerned about someone fixating on their GPS and not scanning for other traffic, though.
