android 2.0 and google's navigation app

Just a quick note on a possible flaw or feature of this app in combination with google latitude (Latitude allows users to sign into google and show their current locations to their friends on google maps, uses phone's gps or a fancy google gears app to get your location on a laptop) You could have users stalking others friends of theirs via latitude and using google's navigation app to guide them get to their friends current location. Now depending on how current the data is or how often google refreshes this data users could possibly have a nightmarish situation.

On the other hand people could play games using latitude and navigation. Catch me if you can!
