It may be cool, but it's not much of an aspiration whilst google earth
remains proprietary software. I'm sticking to Free viewers we have
some control over. 

Similar problem with the map data. It's not ours, we can't do what we
want with it (like publish the results in a journal). We can't use it
offline, and so on (correct me if I am wrong on any of this). So it's
(very) nice, but also highly limited.

Indeed - it is extremely fine, but we do need to be careful not to
make ourselves beholden to other people's data and software.
