Hi
Here is the link to the code.

Vivek,
This approach sounds really interesting.
Are you able to share a small example? Link to working code would be a
bonus!
Also, geocouch is hardly experimental these days, it's at least 2 years old
and has been well used.
A+

Hi
I have been using this approach successfully via a view. The view emits
the geokey based on latitude and longitude of the document (document has a
location).
The idea is to traverse the view in ascending and descending orders - from
a start key corresponding to center of bounding box - and to get sufficient
number of "candidates". Then filter out what is not needed (eg: must be
within a given shape etc.)
I believe using both ascending and descending should solve the 00 and 20
problem you state below.
My best wishes for the geo couch enhancement. No reason why it couldnt be
k dimensional as well...
I just mentioned my approach since it is a common misconception that
multidimensional can not be efficiently mapped to single dimension. I found
the solution to work very well, and it is conceptually simple also.
Thanks

That's an interesting idea but it will not work in all situations. You
could not query for areas that span multiple quadrants. If you would like
to get all locations around 0,0 in a 20km square this won't work.
This task looks suitable for GeoCouch extension:
