My understanding is that the Google map investment also included Keyhole?
Seems like a teraserver via paid content?

I like short responses :-) Google is a classic stovepipe application and
therefore does not need to use certain standards as interoperability behind
the client application is not required. Now, if Google wishes to access and
"fuse" geo content into their application from other non-Google controlled
sources . . . What Google has done has increased overall awareness of
geospatial. They have actually gotten the attention of the large carriers.
This is all good for the industry - including the OGC.
