Why should they be rendered as (mostly transparent) image overlay?
It should be much cleaner by positioning just selected icons, similar
to GeoRSS feed, but with a custom icon.
OpenLayers can show markers from a GeoRSS feed just fine, eg:
http://openlayers.org/dev/examples/georss.html can show earthquakes:
It would require some extension (specifying icon), and while we're at
it, it could it also be used for labels (horizontal place names, not
curly street names) so that they can be dynamically added onto the map
based on the user's language preferences (as determined from
Accept-language http header).
That could be the optimal solution .... at least until all the maps
are fully rendered via SVG (or by other means) on the client anyway :)
