Hi Phil, dear list, Thank you for your response.
I guess I forgot to mention: the idea is to have geometries highlighting on hover / mouse-over... So far, my idea is to indeed use WMS. From there, the map would be augmented by vector rendering, with vector-detail determined by the users' "finite pixel viewport" (map extent => clipping; zoom => simplification). At the min zoomlevel simplifying these complex geometries will allow me to drop 95% of the vertices by simplification, while at the maximum zoom level (full detail) I will be able to drop 95% of the vertices by clipping... My best guess is that internally OpenLayers translates worldly coordinates to screen coordinates before actual rendering; just like I wish to do server side. I'm wondering if the API / Object Model allows for plugging into the rendering stack at that point. If no one on this list has experience in doing so, I will need to study the API carefully... But as a next step, I should consult the OpenLayer-dev list first, i think.
