Sure would be. But it's getting very costly. As for storing you location when you park your car, yes that'd work and it'd be nice to have a simple app that stores a location then later gives you a direction and distance to it. But people never plan to lose their cars and are going to get bored of manually storing the location every time they park. You need something that is a no-brainer. I think there's a new Garmin unit (Nuvi 700?) that provides just this service - it automatically stores the location when you remove it from the car mount. Can the range of bluetooth be extended using this method?
