the development studio lionhead with there title "Black and White" are
probably facing some of these same problems.
here's a preview of the game that i found while searching for the studios
name ;)

Obviously, you'll need to use some kind of LOD.  There's no way you can
even handle a single city with that kind of detail if all is being
displayed at once.  If you look up at the sun from earth, you only see a
glowing yellow-orange ball (well, last time I checked, I don't get out
much) ;). You don't need to actually model the detail from the range
you're at.

Although, the amount of data that needs to be generated to give that kind
of detail will probably entail dynamic, on-the-fly detail, since there's
no way you could store even a single, say, statue or piece of sculpture,
with 1/10000 meter resolution (take a look at the Digital Michaelangelo
project for an idea of the undertaking).

To tell you the truth, I think the idea seems very far-fetched in general,
but that's just my $.02.  :)
