I'm very interesting in this. I'm doint some tests to track station 
positions by using signal intensity values. There are already some 
promising results, in the range of 1.5 to 2 meters for indoors.

But... with hostp i'm getting velus with a high variance under a static 
environment. Furthermore, I'm getting abosulte signal values smaller than 
27 (intepreted as lowest level in the driver) but still rougly 
proportional to the stations's distance. I'm testing with firmware 1.3.4 
and 1.5.6.
