Let me see if I can answer the questions about my planned hike of the Appalachian Trail. I will use Loadstone GPS and Wayfinder Access. Loadstone is a free, open source program. They are not in a position to fund much of anything. Their help in getting, formatting, and showing me how to manage date has been invaluable. We are currently discussing funding with Wayfinder, Nokia, the manufacturers of the Bluetooth receivers I will use, and anybody else we can think of.
