Hi Bill,

Thanks for the quick reply. It's fantastic you guys are so responsive.


The API could be:

data_with_location, radius_points = MappableModel.find(:all, :origin => 
[lat, lng], :within => distance, :return_radius_points => true)

I think it will be good having an option in the find method. I am not 
sure how the radius points should be returned, as returning it to two 
vars is unconventional.

radius_points = [[lat,lng],[lat,lng],...]

FYI. I am using KML with Google Maps. KML wants the coordinates like 
this:
<coordinates>
  -112.3372510731295,36.14888505105317,1784
  -112.3356128688403,36.14781540589019,1784
  -112.3368169371048,36.14658677734382,1784
  -112.3384408457543,36.14762778914076,1784
  -112.3372510731295,36.14888505105317,1784
</coordinates>

Perhaps radius_points can be an object with helper method to_kml:
radius_points.to_kml

What do you think?
