Google has given up control of the newborn they acquired when they bought Keyhole back in 2004. The Open Geospatial Consortium has just officially accepted KML as a standard.
The upcoming IVOA interop meeting in Trieste next month will also have a KML session, where we're going to discuss KML from the astronomy and VO side. I'd like to think that this is the start of the push to adopt KML as an 'official' standard inside the IVOA. Maybe we can sue for partial custody and it can visit us every second weekend and on major holidays?
