Feel free to tell me that I'm totally clueless, as I may well be, but what is wrong with using gpsd for the GPS bit of that? gpsd apparently provides some sort of dbus -- I can imagine that there are things not exposed via dbus that could be, but isn't that a reason to request the extra stuff be added to gpsd's dbus rather than indulging in another round of wheel reinvention?
