Comment 9 for bug 1543483

This needs to be considered very carefully, i.e:
- what shoud be the distance between locations to justify new search? What if the user is moving fast (driving etc.)? Isn't it going to be annoying then?
- what if network goes on and off in the meantime? We don't have good support for that yet in scopes (scopes API has the ability to cache & restore cached results if scope cannot retrieve them, but this needs cooperation from scopes and they don't use this API yet). It may be annoying for the user to have scope refresh automatically as he moves if network is not stable and he ends up with empty dash.
