So you are using Mapserver already! You just have to configure it to
serve it as WFS/GML, and use OpenLayers.Layer.GML instead of
OpenLayers.Layer.Mapserver.Untiled. The PointTrack layer cannot get the
points from an image...

The dataFrom property has nothing to do with the source of your data. It
only tells the PointTrack layer if a line feature should get the data
from its source or target node.

This is the interesting line. In the example, "rss" is the layer that
contains the points. In your use case, this would be the GML layer with
your points.
