Thank you!
The circles are now scaling properly on each zoom level:

How can I adjust the hover effect (keep the same size)?

Bjorn,
your requirement is covered by the new OpenLayers.StyleMap.
First of all, have a look at the styles-context example
(http://www.openlayers.org/dev/examples/styles-context.html).

In this case, though, there are no rules or filters to worry about; I'm

Hi David,
I will consider thematic mapping with WMS at a later stage.
"European Interactive Atlas Explorer" is a good example:

The disadvantage is lack of interactivity on the client.

Hi Matt,
I'm currently implementing your suggestions. I'm able to size the
symbols as a function of the initial zoom level, but I can't figure out
how to attach an event handler to the endzoom event. How can I add an
event handler which makes a function call?

The correct way to handle this is to attach an event handler to the endzoom
event.
This event should manage the size of the symbols so that they are
propotionally sized.
Choose the zoom level at which the symbol renders at the right proportion,
this will be your refernece zoom level. Then si
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.

Hi,
I'm currently testing the capabilities of doing thematic mapping with
OpenLayers.
This is a proportional symbol map based on GeoJSON encoded data:

My question: Is there a way to keep the relative size of the symbols
