I ended up writing something based on how mutiny works and it seems to work
quite nicely... haven't tried with lots of data yet though.

Will this box always have 4 points? Will it be a square with right
angles? if it's going to be that simple, just write the function
yourself.

Because of the way a geohash is created, chopping off charactors off
the end reduces the percision of the 'point'
So a given geohash actually represents a box. The more charctors the
smaller the box.
And because you can do prefix searches on AppEngine, you can just
store the location as a Geohas
How does geohash help one query a bounded box? Geohash is a single point.

As far as I know there are no simple methods. Maybe AppEngine will
include geospatial index type using GeoPtProperty automaticaly in the
future, but alas it doesnt yet. (There is a feature request in the
tracker you should star)
The one in mutiny is pretty good and should work for many uses, and
