While I do think it's a step up from Find My Friends in that you can share your location with people who aren't on iOS, is the underlying technology really any different than Find My Friends? When I pull Find My Friends up, I'm fairly certain it's doing exactly what this "killer feature" relay technology is doing. The app tells me when the location was last grabbed, and it appears to refresh a friends location when I ask to to rather than a continual update (where the user's phone is pushing its location). Although, I may be wrong about how the Find My Friends app works.
