The gnuplot examples in the paper has worked well for me (pg. 20  
graphs) with kismet.  To extend it, overlay a floor plan or google  
map and use a touch screen to take measurements.  W/o a point-of- 
reference, then you'll have to map out X,Y coordinates on your own  
while taking readings, which kind of sucks [1].  I guess could you do  
rough mapping w/ a touch screen if you walked a shape (e.g.  
equilateral triangle) and did rough estimates on the distances (e.g.  
1 meter).

This Hilti tool rocks for taking good range measurements.  That, plus  
graph paper is all ya need (but it's cumbersome).
