[OpenLayers-Users] Proportional Symbol Mapping

[David Fawcett]

I can think of another option, but it is a fairly big change of course.

Instead of sending RSS to OpenLayers and building the vector features, you
could use MapServer to create a transparent WMS layer with your features in
it.  That way, you could use LAYER SYMBOLSCALE to scale your symbols.
