I would like to make the contrary point: OGC wants to have KML support 
in several FOSS4G projects (Mapbender, Mapbuilder, ...), but they do not 
really care how that will be implemented. They have funded many projects 
with little money. Too little money to get distinct implementations of 
well-featured KML support in every single project, UNLESS the projects 
join together and decide for one library to use, integrate and develop. 
That library might be OpenLayers. We should decide. Which other FOSS4G 
projects work on OWS-5 KML client? Anybody know? Given we decide for 
OpenLayers, the projects themselves should allow for the integration of 
OpenLayers as map tool library and OpenLayers should push forward KML 
support, maybe getting partial funding from the OWS-5 funded projects. 
Seems like an OSGeo / FOSS4G showcase to me.

How many days would you reckon it would take someone to integrate 
polygons and basic styling into OpenLayers? Is OpenLayers interested in
