bluetooth golf player alignment application?

Tweet

I would like to develop a tool ( I think bluetooth may be the technology) help me get my golf stance perfectly parrallel and square before I swqing for my practice sessions. I was thinking of placing a transmitter behind the tee, another one about a metre from the ball in the line of the target. Receivers in my shoes and on my shoulders could then calculate whether I am square to the target line... that sort of thing.... I have no idea where/ who to talk to get discuss further... anybody got ideas?
