These are the 3 clues all leaving more to wish:
1. mutiny.appspot.com is the official geopt app but has gears
dependency.
2. My similar (experimental) function filters according to lat/lng as
below.
adds = Adds.all()
L=[]
range = float(self.request.get('range'))
for t in adds:
if t.geopt:
if t.geopt.lat < range + float(self.request.get('lat')) and
t.geopt.lon < range + float(self.request.get('lng')) and t.geopt.lat
> float(self.request.get('lat')) - range and t.geopt.lon > float
(self.request.get('lng')) - range :
L.append(thing)
3. geohash libraries might be more useful or a feature request issue
filed. It's an interesting issue.
Cheers
