It's a hack I did in a few minutes, but here's a script I wrote:

#!/bin/bash
# Usage: gnome_user_list.sh filename lat_min lat_max long_min long_max

lat_min=$2
lat_max=$3
long_min=$4
long_max=$5

while read lat long user; do
  # Strip leading #s, bc doesn't like them
  lat=${lat#+}
  long=${long#+}

  if (echo "$lat $long $user" | grep -v '\.[0-9]*\.' > /dev/null) ; then
    in_range=`echo "( $lat > $lat_min ) && ( $lat < $lat_max ) &&  (
$long > $long_min ) && ( $long < $long_max )" | bc `;
    if [ $in_range -eq 1 ]; then
      echo $lat " " $long " " $user;
    fi
  fi

done < $1

Run it like this with a list of names in the raw text format from the wiki:
dneary sligo:~/src/gnome$ ./gnome_user_list.sh gnome_users.txt 36.9 49.5

Out pops everyone in the latitude/longtitude range that you specify on
the command line.

Cheers,
Dave.
