That script does not plot individual APs in real time either, but it is ready to do that once Network Stumbler is updated to call the OnScanResult script entrypoint. Right now, all any script gets is a count of the new and known APs since the last scan, and the best SNR of all of them. Stumble-map-track uses these counts to plot the circles. I had hoped it may be actually plotting AP range rings, which currently is only possible with post-processing of a NS text export file.
So, being a newbie to the forum (and wardriving in general), I didn't read through everything to see that something similar had been done.
I think I actually tried that script, but it didn't work for me (probably due to other problems).
