What is the criteria which makes 1..n identical points individual records?
First thought would be a filter, i.e.:
FILTERITEM "TIME" # where time is the name of the time column in the
shapefile's dbf
FILTER "%time%" # whatever comes through the URL as "&TIME=timestring&";
timestring is the value passed to the filter
Hope this helps
