too late/risky for 1.6

Comment by Eliot Horowitz (Inactive) [ 06/Jul/10 ]

Everything involving distance will be spherical, maxDistance, etc...

Comment by Andrei Zmievski [ 06/Jul/10 ]

Is this just returning the proper distance in the results or does it also support limiting the results by the radius/maxDistance (expressed in kilometers instead of dimensionless units like now)?
