Sort of MapServer related . . Stacked, or coincident points . . .

[Bob Basques]

All,

I need a way to handle a stacked point data set.  I'm working with a 
Address dataset that has some points that are stacked in the same spot.  
A few of them have hundreds of points in the same location, IE Apt. 
Buildings, etc.

Has anyone worked with a similar dataset before from MapServer?

We have some ideas about how to display the data.  Nothing concrete 
yet.  The current system relies on ImageMaps for the display of the 
point data via a MapServer Template.  This works for the first (last 
ImageMap record) in the imagemap, but how to view the other point 
records from the same point.   We're in the mode right now to build some 
Javascript handlers for a XML stream from MapServer, but this seems like 
overkill for some reason.

The dataset is such that I can't seperate the different points very 
easily, nor should they I think.

Any ideas out there?
