If I had to implement this, I'd use OpenLayers' getFeature control
with a WFS or MapFish protocol, and a singletiled raster WMS layer to
display the points. The WMS layer would be periodically refreshed to
display updated locations.

See for instance http://openlayers.org/dev/examples/getfeature-wfs.html
