@chip,

I had a look at the aritcle on planed neil's site. Also very interesting article.
I think this technique is /will mostly be used in dark circumstances where you want to get as much ambient light as possible. This is done by playing with the shutter time.
One question i have is when you slow down the shutterspeed, will the flash then freeze the subject? Else you'll get a lot of motion blur in the photo.
