I think we can virtually guarantee that KML is going to become a  
standard in the astronomical community. It needs some extension, but  
crucially these extensions have to be kept simple and (crucially I  
think) light weight (and if possible useful outside astronomy).

Google has given us a new IVOA standard, it's KML, and we'd better  
get used to the idea.  Possibly the IVOA should accept the status quo  
and officially adopt it. It might give us a (very) little bit more
