Seconded. There are tools (vs. toys) available for those with the prerequisite skills to use them properly. Providing a point-and-drool -interface to those that lack the skills is not a good idea, it only enables people to play with stuff they do not properly understand and potentially cause all sorts of trouble for themselves and others.

Now, wardriving for fun and "cool-factor" might be a benign activity in almost everyones eyes (some lawmakers seem to disagree however... Maybe it's because telling the ones just looking for benign fun apart from those that have "other motives" is kinda hard and the benign-fun-seekers are a diminishing minority) but doing it with an app that any idiot can use seriously detracts from the cool-factor (if it takes zero "skillz" then what is the cool-factor ?) and the fun gets old really quickly (you're not looking for poorly secured networks to exploit in one way or another for whatever reasons. Or are you ? [but then it won't be for benign fun anymore...]).
