It is possible to start an open service, with mirrors. Interested people can set their freerunners to send in good aiding data when they have it (i.e. when using the gps and a network is available.) Such a update gives away where you are, because the satellite constellation is only seen from part of the world. But I believe this part is large enough for privacy. People using the service don't need to give away much. In an extreme case they will download ephemeris data for _all_ satellites, and then do the processing based on approximate location in the phone itself.
