At this point, the test program doesn't do all that much. The main advantage it offers is that it's a little friendlier than running programs on the command line. Wth the text-only access, you could run this program on a tiny little embedded box and check on its output remotely. Furthermore, the automatically-updating display lets you monitor a network over time. The display isn't very useful, but you can at least have some of the most important data up and monitor the status of the network.
An obvious path for future development is support for WEP keys. Other network monitoring features might be nice; for instance, you might want it to recognize whether the base station that showed up is the one that should be there, so as to detect spoofed base stations. I'll add some of this functionality in the next installment of this series.
