Just a minor point, but I guess you have thought already about it.
Hiding *is* showing.

The center of a 200m disk will show where the house is. With an  
accumulation of enough tracks on time, it will show a higher  
probability. 200m must be also something like 20 houses max?  
(depending on the density, distribution)
Sometimes it's almost better to create random points aka hiding by  
white noise.

just thoughts from the top of my head.
