The problem is that once you assign a group of IP numbers to a geographic 
region, and they're being used, then what happens with population shifts?

For instance, let's say one county in South Dakota gets maybe a /22 
block, and Silicon Valley gets a /6 block.  What happens (hypothetically, 
of course) if all of South Dakota all of the sudden begins growing as a 
techology center?  After you're out of address space, you're out... =)

With IPng, assignment would be better possible, but right now, anything 
close is just improbable.
