Thanks for your time, a couple more questions...
1) Can you please explain how the log file and KML data is stored. In other words, how do we parse or access the information from our web application by time/date? This would apply to A) current vehicle location and B) a daily route up to 25 stops showing the stop points and breadcrumb trail. Can it be saved into a webroot?
2) I noticed in Google Maps Mobile on my phone if I select driving directions it shows point A/B and a blue track line between the two points. Does the KML output support Google Mobile Maps *line tracks*. Or is this something we would add to the KML file when loading it?
