I guess I can give you access in the meantime. What is your github id?

Fair enough :-)

Ah ha, cool. I find the navigation a bit hard, but it's sure quite
interesting
With a bit of love to improve a bit the GUI a preview such as this one
would make quite the showcase for GeoServer.
Btw, I'd change the output format from text/html to something like
application/x3d or application/x3dom, so that it's
evident what we are getting back. In the end application/openlayers also
produces a html no?

Right... or it will work with Google Earth desktop edition too, right?
Btw, I've tried stating "application/vnd.google-earth.kml+xml" as the
output format, but it did not work.
Checked the caps document, can't find the list of supported output formats

Right, so a new output format should be written for it?

Nice thanks
